Thanks. If you have an estimate of how long this would take to get the slice timing information, that would be great.

We have also noticed that many datasets have a TR of 1.0 seconds and considered this to be unlikely. I wrote this short script to look at the NIFTI header for a TR of 1. Within the 3T data, 147 rest EPI datasets seem to have a TR of 1.0 seconds. Do you have information about this as well?

#!/bin/tcsh
# findTR1.csh
set tr1_dsets = 0

foreach rd (rest*.nii.gz)
nifti_tool -disp_hdr -infile_spec $rd |grep pixdim |grep "1.0 0.0 0.0" \
>& /dev/null
if ( ! $status ) then
echo "$rd has TR=1"
@ tr1_dsets++
endif
end
echo ""
echo "Found $tr1_dsets with a TR of 1"
