MemSurfer is a software tool to compute bilayer membrane surfaces.

MemSurfer, Version 1.1

Released: April 19, 2022

Author: Harsh Bhatia ([email protected]) and Peer-Timo Bremer

MemSurfer is an efficient and versatile tool to compute and analyze membrane surfaces found in a wide variety of large-scale molecular simulations. MemSurfer works independent of the type of simulation, directly on the 3D point coordinates, and can handle a variety of membranes as well as atomic simulations. MemSurfer provides many in-built analysis tasks, such as computing the membrane curvature, density and normals of lipids, and area per lipid. More importantly, MemSurfer provides a simple-to-use Python API that may be easily used/extended to perform other types of analysis.

Dependencies

The interface to MemSurfer is provided via python 3, whereas the core functionality is written in C++ 11 with the following dependencies.

1. The Computational Geometry Algorithms Library (CGAL): v 4.13.0
2. boost: v 1.66
3. Eigen: v 3.3.9

Installing MemSurfer and its dependencies additionally require the following software.

• C++ compiler that supports C++ 11 and OpenMP (tested with GNU gcc 7.3.0 and GNU gcc 7.5.0)
  • Please use gcc@7. See known issues below.
• Python 3 interpreter (tested with 3.9.12, 3.7.11, and 3.7.2)
• Cython (tested with 0.29.10 and 0.29.24)
• Swig (tested with 3.0.12 and 4.0.2)
• CMake (tested with 3.13 and 3.20)
• gmp (tested with 6.2.1)
• mpfr (tested with 4.1.0)

All the additional packages (unnumbered) are usually available on all machines through standard package managers, for example, macports, apt-get, yum, etc. Please make use of these package managers to avail these dependencies.

The numbered dependencies may not be available, or package managers may not give full control on the version number to be installed. Here, we will discuss the installation of these major dependencies.

Installation via Spack

Currently outdated and broken. To be fixed soon.

Installation from source

MemSurfer can be downloaded using the following link.

$ git clone --recursive [email protected]:LLNL/MemSurfer.git
$ MEM_HOME=`pwd`/MemSurfer

1. Installing MemSurfer's Dependencies

The following describes the installation of cgal,, boost and eigen, whereas the rest of the dependencies are assumed to be standard and available.

1a. Eigen, Boost, and CGAL (on mac)

On macosx, the simplest way to install these is using macports. As of Jan 2019, macports installs the correct versions.

$ port install cgal           # also installs boost and eigen

1b. Eigen, Boost, and CGAL (from source)

A helper script $MEM_HOME/install_deps.sh is provided to install these dependencies. In order to use this script, you need to specify a C++ compiler that supports OpenMP.

$ export CC_COMPILER=`which gcc`
$ export CXX_COMPILER=`which g++`
$ sh install_deps.sh

This script installs all these dependencies in a folder called $MEM_HOME/external. Note that you may not need to install all four of these dependencies. Please edit the script (lines 6--8) to select which ones to install.

Once installed successfully, please add the following to your shell profile to access these dependencies.

$ export PYTHONPATH=$MEM_HOME/external/lib/python3.x/site-packages:$PYTHONPATH

# LD_LIBRARY_PATH for linux
$ export LD_LIBRARY_PATH=$MEM_HOME/external/lib:$MEM_HOME/external/lib64:$LD_LIBRARY_PATH

# DYLD_LIBRARY_PATH for mac
$ export DYLD_LIBRARY_PATH=$MEM_HOME/external/lib:$MEM_HOME/external/lib64:$DYLD_LIBRARY_PATH

2. MemSurfer

Once the dependencies have been installed, MemSurfer can be installed using distutils. However, you need to explicitly supply the path of the external dependencies.

$ export BOOST_ROOT=<path_to_boost>   # boost headers are contained in $BOOST_ROOT/include/boost
$ export CGAL_ROOT=<path_to_cgal>     # cgal headers are contained in $CGAL_ROOT/include/CGAL
$ export EIGEN_ROOT=<path_to_eigen>   # eigen headers are contained in $EIGEN_ROOT/include/eigen3

Note that, all these paths default to $MEM_HOME/external. So if you installed the dependencies using the script provided above, you do not need to specify these paths.

$ cd $MEM_HOME
$ CC=`which gcc` CXX=`which g++` LDCXXSHARED="`which g++` -bundle -undefined dynamic_lookup" \
  python setup.py install

Trobubleshooting and Known Issues

Jul 20, 2021: It appears that compilation using gcc@8 results in a segfault or a malloc error (see issue #10). The problem appears to be residing in a dependency called pypoisson. Until it is resolved, please use gcc@7.

Jan 23, 2019: If the cloning fails with the following error:

Cloning into '<your-path>/MemSurfer/pypoisson'...
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

This error means that your ssh keys are not registered with github. Please see here and here to register your ssh key and retry.

memsurfer's Issues

Problem to import memsurfer

Hi All,

I have successfully compiled memsurfer, after building locally GMP and MPFR libraries in the $MEM_HOME/external folder.

I try to import but I get the following error:

I would like to use local versions of GMP and MPFR since I am compiling for our local modules server.

Best regards,
Jose

Format of output files

Is it possible to save the output data in either VTK or numpy array format instead of the VTP format?

libCGAL not found on OSX

I'm attempting to install MemSurfer via the online instructions, and wound up with a problem when I attempt to actually run the installation script. I installed CGAL via homebrew, however, this is a header-only library, and so when I try to setup MemSurfer I get the following error:

  > MemSurfer = (/Users/cedelmaier/Projects/Biophysics/MemSurfer)
  > CGAL_ROOT = (/usr/local/Cellar/cgal/5.4/)
  > EIGEN_ROOT = (/usr/local/Cellar/eigen/3.4.0_1/)
  > BOOST_ROOT = (/usr/local/Cellar/boost/1.78.0_1/)
Traceback (most recent call last):
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 160, in <module>
    PATHS = fetch_paths(os.path.join(PATH_MEM, 'external'))
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 106, in fetch_paths
    paths['cgal'].update({'lib': find_shlib_path(paths['cgal']['root'], 'libCGAL')})
  File "/Users/cedelmaier/Projects/Biophysics/MemSurfer/setup.py", line 63, in find_shlib_path
    raise Exception(f'Find_shlib_path({path},{libname}) failed!')
Exception: Find_shlib_path(/usr/local/Cellar/cgal/5.4/,libCGAL) failed!

So really, need to know if the library is really needed, or change the installation instructions for the brew installation version to accommodate the different installation types.

Proplem for installation

When I finished installation of first step —— Installing MemSurfer's Dependencies，The python3.x folder does not appear in the Memsurfer/external/lib/ folder。

so，I don‘t add the the following to my shell.
export PYTHONPATH=$MEM_HOME/external/lib/python3.x/site-packages:$PYTHONPATH
then, I continue to the next step——install MemSurfer。
when I finished ，I open python environment， and import memsurfer。 but the following problems occurred。

Am I doing something wrong in the first step, or the second step?

import error

Hi,

It seems that I have installed the MemSurfer, but I am getting the below error while importing the memsurfer. A similar issue has been reported previously (#3), and I am not sure how to implement the corresponding changes in the new/current setup.py file. Please find the attached setup.py file. I tried to add the 'GMP libraries as suggested in issue #3; still, it didn't solve my issue. I am new to python, and any help will be appreciated.

can you help me to solve this problem?

BUG: double free errors

Probably there should never be double free C++ errors, regardless of the input data, if the memory handling is safe throughout the library and its dependency stack.

Here is a reproducer using nothing more than NumPy, pytest, and the hypothesis[numpy] property-based testing library:

Run the test below with version 1.0 of memsurfer with: pytest reproducer.py -s

import numpy as np
import memsurfer
import hypothesis
from hypothesis import given
from hypothesis import strategies as st
from hypothesis.extra import numpy as hynp


@given(
      # generate the leaflet coords
      hynp.arrays(np.float64, (100, 3)),
      # and the box coords
      hynp.arrays(np.float64, (2, 3)), 
      # and the resnames
      hynp.arrays(np.str_, 100),
        )
def test_memsurfer_double_free(leaflet_coords, bbox, labels):
    # this test causes memsurfer or one of its
    # dependencies to produce C++ "double free"
    # errors
    memsurfer.Membrane.compute(leaflet_coords,
                               labels=labels,
                               bbox=bbox,
                               periodic=False)

It will hard crash:

Import error- undefined symbol: __gmpq_add

When I'm importing memsurfer, I get the following error:

ImportError: /home/nambinik/miniconda3/lib/python3.11/site-packages/memsurfer-1.1.0-py3.11-linux-x86_64.egg/memsurfer/_memsurfer_cmod.so: undefined symbol: __gmpq_add

I believe this might be due to the GMP library not being linked,

With inspiration from an earlier question #3 I added the libgmp libraries to setup.py and reinstalled memsurfer.

Specifically changed lines 228,234 and 235

include_dirs=[PATH_PM, numpy.get_include(),
PATHS['boost']['include'],
PATHS['eigen']['include'],
PATHS['cgal']['include'],
'/opt/local/include','/usr/include/x86_64-linux-gnu'
],
LIBS_EXT.append('gmp')
libraries=LIBS_EXT,
library_dirs=[PATHS['cgal']['lib'],'/usr/lib/x86_64-linux-gnu/']

Still get the same error though. How would one go about getting around this error?

libCGAL.so not found in building

I am having the same issue described in #20 on a Oracle Linux 8 system. CGAL 5.6.1 is header-only and a devel package with the library is not available. It is not possible to build libCGAL.so using the source distribution. Has any progress been made to eliminate this library dependency?

ImportError with spack MemSurfer with undefined symbol: __gmpq_set_si in shared object file

Hi,

I installed memsurfer with spack, but encountered an error when importing the module. I am using Ubuntu20.04 on Windows Subsystem for Linux 2 (WSL 2). I believe my issue is related to #12 , except I did not build memsurfer manually. Please find the error traceback below. Any ideas on what went wrong?

Thanks!

The commands I entered to install and import memsurfer:

Computing surface yields unexpected error

Hello,

I'm trying to compute a surface for a CG pure POPC membrane.
In pseudocode, the procedure I'm following looks like:

import MDAnalysis
from memsurfer import Membrane

u = MDAnalysis.Universe(pdb_file, xtc_file)

frame = u.trajectory[-1]

atoms = u.select_atoms('name PO4')
bbox = np.zeros((2,3))
bbox[1,:] = frame.dimensions[:3]

membrane = Membrane.compute(atoms.positions, atoms.resnames, bbox = bbox, periodic = True)

Which yields the following error

terminate called after throwing an instance of 'std::length_error'
what():  cannot create std::vector larger than max_size()

It looks like it has something to do with the box dimensions (maybe?) but I have no Idea how to fix it.

I also tried computing a surface from a random distribution of points within the same bounds as my membrane, and get the same error.

Thank you very much in advance for your help!

Import Issue

Hi,
I followed the instructions on the installation of memsurfer, but when I try to import memsurfer I get a ndarray error. I wondering if I could get some help on this. This is the error that I receive.

installation: import issue

Hi,

I have installed Memsurfer 1.1.0.
setup.py ran successfully. But when testing with a simple script "test_install.py", containing just one line:

import memsurfer

then I get the error:

Traceback (most recent call last):
File "test_install.py", line 1, in

notes and related issues:

• the error is similar to issue #3, but the setup.py file has been changed since, so the solution cannot be applied.
• This issue might be essentially the same as issue #12 , which is unsolved.
• I read issue #23, and have ensured that I was not in the source dir when trying to import memsurfer
• OS version: Ubuntu 20.04
• python version: 3.8.10

kind regards,
Andreas

Change "resolution" of measured curvature

Thanks for the nice tool! After playing with it, I have managed to obtained the parametrized surfaces for a given simulation I have. I am interested in measuring the "major" curvature though, and it seems the calculation is done at a very "local" scale, and there is no way of measuring the curvature of the overall membrane, i.e., the workflow identifies imperfections in the membrane, but not real membrane curvatures. Is that the case, or am I missing some function available to do this?

Adding MemSurfer to Conda

Hi, thanks for the very nice package! I am just wondering whether you have any plans to make it available via Conda, specifically the conda-forge channel? I have not added pacakges to Conda before, but would be happy to help figure out how so that others can more easily install MemSurfer.

Importing the module after building fails

I have installed memsurfer using spack. GMP and MPFR were installed in the machine. when i was looking for solution, found this thread in the issues (#3) but i don't know how to implement this with spack.

Best regards
Satya Chaithanya

Build on Ubuntu16.04 requires several dependencies not satisfied by install_deps.sh

The GMP package and MPFR packages are required to build the CGAL core libraries and are not installed prior to the attempted CGAL compile.

Manual installation of GMP and MPFR may be required on some platforms, or possibly circumvented by installing CGAL using apt
"sudo apt-get install libcgal-dev"

and pointing MemSurfer in the right direction using
export CGAL_ROOT=<path_to_cgal>

Other than that thanks for all the hard work.

Hi,
I do not really know what happened here. Help would be very appreciated.

cgal error installation from source OSX

1. I installed MemSurfer from source utilizing the README protocol:

$ git clone --recursive [email protected]:LLNL/MemSurfer.git
$ MEM_HOME=pwd/MemSurfer

2. After installing dependencies,

$ export CC_COMPILER=which gcc
$ export CXX_COMPILER=which g++
$ sh install_deps.sh

3. I ran into the following issue with CGAL installation:

Can you help me with next steps in this installation?
