Overlapping timestamps on x-axis of carpetplot for 1-2 (of 7) tasks

[c-spelman]

What happened?

Hi all. I’m using fMRIPrep 23.2.1 (via Neurodesk) to preprocess my fMRI data. I follow the same steps and use the same script for all participants (N = 36). When looking at the .html outputs and doing my Quality Check, I noticed about half of my participants have overlapping timestamps on the carpetplot for 1-3 tasks. I've added screenshots below with a yellow rectangle around the overlapping values.

Note that the order of tasks does not seem to matter. I have 7 tasks that populate in alphabetical order in the .html output. Various tasks are impacted for each participant; it does not seem to be task-specific, and some participants show this overlap for one task, while others show it for two tasks. I've tried re-running a participant using the most recent version of fMRIprep, and the output resulted in overlapping timestamps for a different task than the one from the output of version 23.2.1. This data has also been collected over several years, and various participants are impacted (not just ones collected within a specific month/semester/year).

I'm on a MacOS computer and have updated my Docker memory settings to CPU limit: 12, Memory limit: 24 GB; Swap: 4GB; Disk usage limit: 1TB.

I've re-run one participant a total of 3-4 times, and each time results in different tasks being impacted; the error is not consistent, even for the same participant.

I've posted in Neurostars and on the GitHub page for Neurodesk. The Neurodesk page recommended I clear my Neurodesk home directory via Docker, which I did. The overlap still occurred in the output (for a different task than before). They recommended I post the issue here.

Any insight or suggestions would be greatly appreciated!

Does this occur in the latest version?

Hi @effigies - yes, it still occurs in the latest version of fmriprep. I re-ran a participant using the most recent version. The previous .html output showed this overlapping timestamp for two out of the seven tasks. Re-running on the most recent version fixed the overlapping timestamps for those two tasks; however, now, a different task has overlapping timestamps on the carpetplot.

It seems like the figures probably just need to be explicitly closed in the interface that creates them. I think should be a pretty simple fix.
