save stim file

[CerenB]

is it possible to create two different output file? e.g. .tsv file for stimulus and .tsv file for tapping

[Remi-Gau]

like one with stimulus and the other for the responses (is that what you mean by tapping?) ?

[CerenB]

yes, since not in every stimulus participant will press. so i want to keep these two separated. but I guess the function is doing it... though I'm not sure. Since there's only 1 time you used "open" input in visualLocTranslational.m I thought you may not save two separated files?
Definitely a better readme could have made my day easier :D

[Remi-Gau]

yes I need to give more explanation there.

but your approach is definitely possible and some of the code can be reused for that purpose.

let me check if there is a way to make that even fit within the BIDS framework.

Physiological and other continuous recordings

Template:

sub-<label>/[ses-<label>/]
    func/
        <matches>[_recording-<label>]_physio.tsv.gz
        <matches>[_recording-<label>]_physio.json
        <matches>[_recording-<label>]_stim.tsv.gz
        <matches>[_recording-<label>]_stim.json

Optional: Yes

Where corresponds to task file name without the _bold.nii[.gz] suffix. For example: sub-control01_task-nback_run-1. If the same continuous recording has been used for all subjects (for example in the case where they all watched the same movie) one file can be used and placed in the root directory. For example:task-movie_stim.tsv.gz

[Remi-Gau]

Would it make sense to use the _stim.tsv option in your case?

[CerenB]

maybe I should open a new issue but does it say anything regarding to duration for behavioral exp?
In saveEventFile.m there's duration to be saved but is it necessary for behav exp?

https://bids-specification.readthedocs.io/en/stable/04-modality-specific-files/07-behavioral-experiments.html

[Remi-Gau]

duration is just how long each event was : for responses I would put 0

[CerenB]

OK! so I shall define duration = 0 in my main script and then call saveEventsFile function.
Then _stim.tsv sounds ideal. How shall I implement that?

[Remi-Gau]

Will open a pull request and let you review it: does that make sense?

[CerenB]

sure!

[CerenB]

I think so far the changes were made was on createFilename.m but maybe for a cleaner logging of the behavioral experiment(s), I might need some changes in SaveEventFile.m. such as if in beh modality, duration and onset could be done optional.

[Remi-Gau]

I think that for the events file to be BIDS compliant we might need to keep the duration and onset columns, but I could check if the it is still OK to fill them with N/A or NAN.

[CerenB]

OK!
