Thanks Francois for all the useful comments. Regarding tutorials, how about a section for flattening right after the [Unconstrained orientations](https://neuroimage.usc.edu/brainstorm/Tutorials/SourceEstimation?highlight=%28unconstrained%29#Unconstrained_orientations) section in the source estimation tutorial, or in the advanced...

Thanks @juangpc for suggesting this and working on a solution. Unfortunately I'm not a Git guru like @martcous, so I don't have much to contribute, but I just wanted to...

Hello! The .eeg file inside CTF .ds folders can also be empty. Could it also be added as an exception?

I've also seen some backup files that are created by CTF software that can be empty: e.g. bad.segments.bak, or *.eeg.bak. I believe that's it for potentially empty files. Note that...

Do you mean just for the .bak files? Note that they show up quite often, even for data that was not really processed in any way. Just renaming a dataset...

I'd suggest adding *.eeg and *.bak to the exception as an immediate step. But maybe there needs to be a broader discussion about the check itself.

Sorry, .eeg is only the extension. The actual file name for the CTF .eeg file is for example: sub-0001_ses-0001_task-rest_run-01_meg.ds/sub-0001_ses-0001_task-rest_run-01_meg.eeg It must have the same name as the .ds folder (as...

I'd rather suggest not enforcing this empty file rule by default. I think it's fine from my perspective that this tool would not fully validate all data formats in all...

> Are `.bak` files only expected to be in `.ds` folders? Yes for CTF datasets. I agree with everything in the last post. If someone implements a CTF validator, then...

Thanks! I manually updated the geom format and now I'm getting a new error: ``` Executing using 4 threads. | ------ C:\Users\Marc\.brainstorm\openmeeg\win64\om_assemble | -DSMNA | F:\Sync\Research\DARPA\Rat\openmeeg.geom | F:\Sync\Research\DARPA\Rat\openmeeg.cond | F:\Sync\Research\DARPA\Rat\openmeeg_dipoles.txt...
