Creating RVT and HR slice based regressors with multiband data.

[Avijit-Chowdhury1]

Hi experts,

I have physiological data collected with Labchart and saved as Matlab file (.mat). Scans were collected in multiband sequence and I have the slice timing file. I would like to generate the RVT and HR regressors using Physio toolbox functions. Currently, I have the filtered respiratory and ECG time course.

How and where can I specify my slice timing information?

Does anyone have any suggestions to derive these regressors using physio toolbox functions?

Thanks

I have read in another post that if I want slice-based regressors (for AFNI), I should put a range for the scan_timing.sqpar.onset_slice = [1:nslices]

Is this correct?

Dear Avijit,

Great you found the answer here in the forum. Let me if it worked!

You can also share the .m file you created to double check the parameters. There are some intricacies with multiband data that have to be considered, also mentioned here in the issue forum.

All the best, Lars
