Failure running hcp_main_milgram_tcp_2023.sh with fmriVol=true for TCP dataset #2

Description

@Tloops

I have completed the preFS, FS, and postFS phases (without errors). So here is my problem:

When executing fmriVol, specifically line 286 of TopupPreprocessingAll.sh, an error occurred when executing fsl/bin/topup:

Topup::topup_clp::topup_clp: Unrealistic read-out time, should be in range 0.01-0.2 s

I carefully checked the read-out time calculation (line 222-266 of TopupPreprocessingAll.sh): Total_readout=EffectiveEchoSpacing*(ReconMatrixPE-1)

However, the value of EffectiveEchoSpacing in the actual script comes from line 266 of hcp_main_milgram_tcp_2023.sh, where DwellTime_fMRI="0.0000021". Therefore, the calculated read-out time is only 0.0002163. Perhaps we should use the "EffectiveEchoSpacing": 0.000580009" entry in the fmap JSON file instead. In that case, the calculated read-out time would be 0.05974, which is in the range 0.01-0.2 s.

Has anyone else encountered a similar problem, or does anyone have other solutions? Looking forward to your replies.
