Stimuli
Video/Audio
TODO: WiP to establish collection and automagic alignment/inclusion in BIDS datasets of video and audio as presented to the participants for all experiments. Envisioned purposes are not limited to
- QA and trouble-shooting:
- did MR collection started in time?
- were there any abnormalities with video/audio stimuli delivery for that session?
- Automated extraction of visual annotations to be used as
- Forward modeling inputs
- Standard GLM explanatory variables
video/audio tracks are to be stored under stimuli/
of BIDS datasets, under
filenames matching corresponding .nii.gz
data.
Video capturing device at hands: Magewell USB Capture DVI Plus (DVI, VGA, HDMI Composite, and Component ) It is accessible in Linux via V4L etc, but for the fine control over USB we need to use proprietary dynamic libraries. Libraries and C++ examples are available within SDK for Linux
Behavioral data
TODO: WiP ... to automagically provide detailed, and temporally aligned to MRI
acquisition, _events.tsv
files for BIDS datasets.
