[FieldTrip] Load BIDS motion data

[Cross, Kathryn A.]

I am trying to load BIDS formatted motion data and am  unsure of the correct way to do this.
When I try to use ft_read_data I am receiving the below error.
Is my input wrong? It seems to be trying to read a tsv file as a json in line 317 of ft_read_header. I have tried a few variations of headerformat and dataformat arguments without success.

Thank you in advance for any advice!

Katy


data = ft_read_data('sub-CM01_task-reaching_tracksys-apdm_run-1_motion.tsv','dataformat','bids_tsv');

208 [filename, headerfile, datafile] = dataset2files(filename, dataformat);
found matching BIDS sidecar 'G:\PROJECTS\Cueing_Noninvasive\data\bids\sub-CM01\motion\sub-CM01_task-reaching_tracksys-apdm_run-1_motion.tsv'
