MRIQC Outlier Frames (FD & DVARS)

[Bram Diamond]

Hello MRIQC users and Dev Team,

I'm new to using MRIQC and would like to know if there is a way to output a binary text file specifying outlier frames given thresholds for FD and DVARS. The next phase of my pipeline uses mkanalysis-sess from the FreeSurfer FS-FAST suite. It can optionally call in a text file for TPs (i.e., frames) to exclude with the tpexclude flag. I've been using this option to exclude frames that exceed FD and DVARS thresholds.

I have successfully run mriqc v0.16.1 on docker at the participant and group levels in my BIDS directory and I'm thrilled about the visual reports. I used the following additional flags: verbose-reports, v, fft-spike-detector, and fs_thresh 0.4.

I couldn't find a way to specify the DVARS threshold. Is there a flag that I've missed? I would also like to know if Is there a straightforward method for extracting the index value of frames that exceed FD/DVARS, or better yet a columnar text file like the one described above.

Thank you for your help.

Cheers,

Bram
