Data for mne-python testing

mne-testing-data

Data for mne-python testing.

Acquire this data in MNE

Use mne.datasets.testing.data_path(verbose=True).

Update to the latest version in MNE

Use mne.datasets.testing.data_path(force_update=True, verbose=True).

Add or change files in the repo for use with MNE

1. Ensure your only option is to add files here. Alternatives would be e.g.:

   • See if you can make use of existing files
   • Synthesize the necessary testing files using e.g. RawArray and NumPy directly

2. If new files are needed, make a PR to this repo to add your files.

   .. warning:: Make files as small as possible while ensuring proper testing! This often means e.g. cropping to a very short segment of data or using a small subset of channels.

3. Update the version.txt of the repo in your PR to the next increment.

4. Once your PR is merged, ask a maintainer to cut a new release of the testing data, e.g. 0.53.

5. In MNE, update mne/datasets/config.py to:

   1. Change the 'testing' value in the RELEASES dict in mne/datasets/config.py to the new version.

   2. Set the new hash. This can be easily done by either:

      1. Downloading and running md5sum on this (with the proper version number):

         https://codeload.github.com/mne-tools/mne-testing-data/tar.gz/0.53

         or

      2. Force-updating the repo and looking at the error message (as it gives the new true hash), e.g.:

         $ python -c "import mne; mne.datasets.testing.data_path(force_update=True)"
         

mne-testing-data's Issues

Add NIRx fNIRS test data for 15.0 and 15.1

I am planning to add two more NIRx measurements. The file format is currently 15.2 which was added in #51 and #52 . I will add a 15.1 and 15.0 recording. The four recordings will then cover all versions of the latest file format. Is this ok? Is it the sort of thing you want in this repo? Or is it more appropriate to put elsewhere?

Anonymized data

SSS data needs to be re-anonymized after MaxFilter processing.

Provide instructions for how to use with MNE

It would be really helpful to add a sentence to the README of this repo instructing people to use mne.datasets.testing.data_path() to download the data from this repo.

SSS test data does not open in graph or mne_browse_raw

I'm having trouble opening the two SSS raw testing files (test_move_anon_raw.fif and test_move_anon_raw_sss.fif). A fairly recent build of mne_browse_raw (2.7.4.2448) complains that each file "does not start properly!" while Neuromag graph complains that "FIFF file should start with FIFF_FILE_ID!". Maxfilter -history reports "ERROR: Cannot open channel info file test_move_anon_raw_sss.fif! Cannot process data (exit value = 3)." Just a heads up.
