Hello,
I'm trying to run 3dTcorrelate with two datasets that have the same number of time points (215) according to 3dinfo -nt, but then 3dTcorrelate indicates that they don't have the same length. Here are the commands
>>> 3dTcorrelate -overwrite -pearson -Fisher -prefix TCORRmap.nii.gz P3SBJ01_Events01_MEICA_RHO0_BIC_SPMG1.dr2HRF_E02.nii.gz P3SBJ01_Events01_DN.FBrain.spm.fitts.IM.nii.gz
P3SBJ01_Events01_MEICA_RHO0_BIC_SPMG1.dr2HRF_E02.nii.gz is different length than P3SBJ01_Events01_DN.FBrain.spm.fitts.IM.nii.gz
>>> 3dinfo -nt P3SBJ01_Events01_MEICA_RHO0_BIC_SPMG1.dr2HRF_E02.nii.gz
215
>>> 3dinfo -nt P3SBJ01_Events01_DN.FBrain.spm.fitts.IM.nii.gz
215
After this error, I tried to investigate possible reasons and noticed that the first dataset (P3SBJ01_Events01_MEICA_RHO0_BIC_SPMG1.dr2HRF_E02.nii.gz) is '-abuc', whereas the second dataset (P3SBJ01_Events01_DN.FBrain.spm.fitts.IM.nii.gz) is '-epan'. Could this be the reason why 3dTcorrelate is not working?
If this were the case, I also tried to change the data type of the first dataset from -abuc to -epan with 3drefit -epan P3SBJ01_Events01_MEICA_RHO0_BIC_SPMG1.dr2HRF_E02.nii.gz). However, although the command runs, it seems that no change is actually done because the dataset continues to be -abuc according to 3dinfo.
Any suggestions would be really appreciated.
Thanks,
Cesar
