How to use the restart command about montepython_public

[brinckmann]

Hi,

The flag you want to use is
-r <file>
which will restart chains from previous run. You must pass the lowest index chains file, e.g. 2018-09-12_10000__1.txt . MontePython will then create copies of all chains index 1 through N (number of MPI processes) with new names 2018-09-12_20000__1.txt etc. Once the chains have been copied the old chains can be moved to a backup folder or deleted. Note they will be automatically deleted at the completion of the run. You should not include the old chains as a part of the analysis.

I will update the help files as it is not very clear. I will also add the alias --restart (which does not currently exist, my apologies!)

For general help on using MontePython our most recent MontePython lecture from the Kavli Institute for Cosmology in Cambridge last month may be useful, you can find them on the website of Julien Lesgourgues.

Best,
Thejs
