Hi all,
An unexpected error:
3ddelay -nodtrnd -maskMSK.nii.gz -nodsamp -fs 2 -T 0 -ideal_file REF.1D -input DATASET.nii.gz -prefix DELAYMAP.nii.gz
Throws an error (or, rather, throws this error as many times as I there are voxels):
__________________________
Error: Initialization problem!
Error origin: hilbertdelay_V2
__________________________
If I use a polort (i.e., delete "nodtrnd"), the error does not occur. If I use a different chunk of that time series (with an appropriately sized chunk of "REF.1D"), and keep "-nodtrnd", the error doesn't occur.
Any idea what might be going on? The relevant part of the ".log" is copied below.
Thanks,
-Daniel
