BytesAvailable_Callback error in digitizer

Bugs
21

Can you try to reload the protocol? => right click on the protocol and then > Reload

Just to confirm, have you are looking at the Brainstorm GUI in the Functional data (iconStudyDBSubj) view rather than the Anatomy view (iconSubjectDB), right? Sometimes it can be easy to overlook.

Hi,

I think that may have been the issue indeed. My apologies for forgetting about this thread and not responding sooner. The original issue with digitization was fixed at this point. However, a new error just popped a few days ago:

Warning: Error executing listener callback for PostSet event on TotalBytesWritten dynamic property in object of matlabshared.asyncio.internal.Channel class:
Intermediate dot '.' indexing produced a comma-separated list with 0 values, but it must produce a single value when followed by subsequent indexing operations.

These errors show up after I finish collecting the fiducials and start collecting the first EEG electrode location. I can make a separate post about this error if that's better, but since it is related, I thought I'll share it here first.

Thanks,

Hi Parth,

What is the version of Brainstorm that you are using?

Also, once the error is showed, can you run these lines and share with us the result:

global Digitize

Digitize.SubjectName

Digitize.ConditionName

Digitize.Points

sSubject = bst_get('Subject', Digitize.SubjectName)

sStudy = bst_get('StudyWithCondition', [Digitize.SubjectName '/' Digitize.ConditionName])

sStudy.Channel.FileName

ChannelFile = file_fullpath(sStudy.Channel.FileName)

Hi Raymundo,

We are using MATLAB R2024b; BST Version: 06-May-2025.

Here are the results from running your suggested lines of code:

sSubject = bst_get('Subject', Digitize.SubjectName)

sStudy = bst_get('StudyWithCondition', [Digitize.SubjectName '/' Digitize.ConditionName])

sStudy.Channel.FileName

ChannelFile = file_fullpath(sStudy.Channel.FileName)

ans =

    'Digitize'


ans =

    'Practice with mannequin-Seti_20250528_01'


ans =

must produce a single value when followed by subsequent indexing operations.

Hello @parthchholak,

The issue was caused by spaces in the provided subject ID:
Practice with mannequin-Seti

The case for non-valid characters in subject ID is now automatically handled, commit: f9b5ef3

Thank you. I can confirm that it is now working at our end as well.
