"SliceTimingCorrected": false in fmriprep

Summary of what happened:

Dear experts,
When I checked the fmriprep result. I found “SliceTimingCorrected”: false in the JSON file. And I checked other posts on Neurstar https://neurostars.org/t/questions-regarding-fmri-preprocessing-with-fmriprep-resolution-time-points-and-dimensions/27947, I think it has some problems. But, the whole process of fmriprep ended smoothly, with no apparent errors being generated. What’s the most likely cause of this problem?
Looking forward to your reply. Thanks advance.

Hi @Yufeng_He,

Is slice timing defined in your original BOLD jsons?

Best,
Steven

Hi steven,
Thanks for your reply. It is my wrong, I rechecked the JOSN file, and It didn’t include slice timing. I don’t know why some subjects didn’t generate the field. I would re-run heudiconv and re-run fmriprep already to check if the problem still occurs. Thanks again.
