I can't think of anything in particular that may cause problems. I would suggest contacting the authors of the other software to see if it is possible that it does not handle square images, or images with dimensions that are not a power of two.

There is not problem to open the file w*.img with SPM, I think that the Bas Gan is not compatible with the NIFTI format. Is there difference any between the r*.img file and w*.img files from the point of view of Analyze file? Because I am able to open the first one but not the second one with Bas Gan.

SPM5 uses NIFTI format, as described at http://nifti.nimh.nih.gov/ . Many other fMRI analysis packages also use NIFTI, but I'm not sure if BasGan is compatible with it. It may be an idea to check whether the w*.img files can be displayed in SPM. Maybe something went badly wrong during the processing.

I would like to use this software with images normalized by SPM but I have problem to open the normalized images (w*.img) produced by SPM. I don' t have problem to open the realigned images (r*.img). Is there in the analyze file produced by SPM normalization some offset or scale fields that are different from an usual analyze file? Thanks in advance! anna
