change what git-annex should annex (source: github copilot)#

To tell git-annex not to annex files ending with .mat, you can configure the .gitattributes file to mark such files as not being large files. Here's how you can do it:

Steps: 1. Open or create the .gitattributes file in your repository. 2. Add the following line to exclude .mat files from being annexed:

*.mat annex.largefiles=nothing

Explanation: *.mat: Matches all files ending with .mat. annex.largefiles=nothing: Tells git-annex not to treat these files as large files, so they will be handled by regular Git instead of being annexed. Example .gitattributes File: Apply the Changes: After updating the .gitattributes file, if .mat files have already been annexed, you need to move them back to regular Git:

  1. Find the .mat files currently annexed:
git annex find --include="*.mat"
  1. Unannex the .mat files:
git annex unannex "*.mat"
  1. Commit the changes:
git add .gitattributes
git commit -m "Exclude .mat files from git-annex"

Now, .mat files will be tracked by regular Git instead of being annexed.
