@GuillaumeFavelier as the next step, can you separate into blockers for 0.24 and non-blockers for 0.24, perhaps working with @agramfort and @hoechenberger ? To me it's just the initial-startup bug I added to the list.
Alright, I'll update the original post and take care of this bug in priority 👍
@GuillaumeFavelier - thanks so much for this refactoring. I'm really looking forward to leaving behind mayavi for coreg.
In updating some of my code, i ran into an issue with the auto coreg method and CTF data. CTF doesn't have unique HPIs (they use nas/lpa/rpa) and the current code assumes these are not None and tries to update them.
Below is an MWE that throws
~/anaconda3/envs/mne-stable/lib/python3.9/site-packages/mne/coreg.py in _update_params(self, rot, tra, sca, force_update_omitted)
-> 1464 apply_trans(self._head_mri_t, self._dig_dict['hpi'])
~/anaconda3/envs/mne-stable/lib/python3.9/site-packages/mne/transforms.py in apply_trans(trans, pts, move)
-> 240 out_pts = np.dot(pts, trans[:3, :3].T)
TypeError: unsupported operand type(s) for *: 'NoneType' and 'float'

raw = read_raw_ctf(ctf_fname_catch)
fiducials = "estimated" # get fiducials from fsaverage
coreg = Coregistration(raw.info, subject, subjects_dir, fiducials=fiducials)
This patch moves past the error allowing CLI coregistration, but I don't know how it interacts with the work you're doing in the GUI or if there is another way you would want to solve the issue so didn't want to open an separate PR.

Best, Luke
The new gui also has a small backward compatibility issue.
The old mayavi GUI supported fif files that only contained dig points.
The new gui has replaced this with a read_meas_info
call
which crashes out on these files.
ValueError: Channel information not defined
Fatal Python error: Aborted
Let me know if you'd like a PR with these two bug fixes, I just don't want to complicate stuff you are already working on.
I'd say go for it @bloyl !
@GuillaumeFavelier given that we plan to cut 0.24 next week (preferably early), do you think the list above marked for 0.24 is realistic?
Indeed, early next week is unrealistic for all of those.
Okay, I'll bump those to 1.0. I think it's okay if a few of these features lag
I am not able to get past this:
from mne.coreg import Coregistration
it throws error: cannot import name 'Coregistration' from 'mne.coreg'
The other function from mne.coreg work well like getting fiducials from fiducials = mne.coreg.get_mni_fiducials(subject, subjects_dir=subjects_dir) but this import Coregistration from mne.coreg fails for some reason. Can someone help me resolve this?
from mne.coreg import Coregistration
To start up the coregistration GUI, you need to call
mne.gui.coregistation()
Yes, but I want to use automated coregistration as explained in MNE tutorial: https://mne.tools/dev/auto_tutorials/forward/25_automated_coreg.html
I have more than 1000 subjects and cannot use GUI to generate trans file every time. So, need to automate this as per above tutorial. So, how should I resolve this error?
@hbk008 I cannot reproduce this with MNE-Python 0.24. Please update to MNE-Python 0.24, then it should work.
Please note that this issue tracker is intended for bug reports and development issue tracking only. For usage questions like yours, please refer to our forum at https://mne.discourse.group
Okay, will post in the forum next time. You meant update from 0.23 to 0.24, right? Anyway, I updated to 0.24 and it worked finally, thanks!
Great to hear it works now!! 👍
I removed the item:
- [ ] add support for a zoom parameter
assuming that it's among the parameters (head_inside
, guess_mri_subject
, ...etc) that we do not need.
