Structural segmentation and normalization
Hi,

I am trying to preprocess my data and it keeps failing at the same structural segmentation and normalization phase saying that a .nii file doesn't exist, but it does exist as .img/.hdr files, and I can pull them up individually with conn and see that they are present and correct data. It seems that it is struggling to pass the necessary files from one preprocessing stage to the next. all of my files are in the analyze format and I am able to get through all of the functional stages. Only this stage has been resulting in an error. Here is the exact error:

SPM12: spm_imcalc (v6124) 02:50:15 - 19/05/2017
========================================================================
Failed 'Image Calculator'

Can anyone offer some tips?
