@me-sh, thank you for the PR! Please add tests. See the other SRM tests:
https://github.com/brainiak/brainiak/blob/master/tests/funcalign/test_srm.py
You can use the Pytest tmp_path fixture to obtain an output directory:
https://docs.pytest.org/en/latest/tmpdir.html#the-tmp-path-fixture

I made some minor adjustments and added a test of the SRM save/load functionality here: me-sh#1 (not sure how to commit changes more directly to this PR)

Thanks, @snastase! You should be able to push your branch to @me-sh's.

git remote add me-sh https://github.com/me-sh/brainiak
git fetch me-sh
git push me-sh

Because we are planning to make a release very soon, I will add @snastase's commits to this PR and merge it.

Thanks @snastase and @mihaic !

No, thank you, @me-sh! :)

And thanks for the quick help, @snastase.
