Dear All,
I have been using SPM99 to analyze some fMRI data and am now moving to SPM2. I did all the data
preprocessing using some batch scripts. I generated some contrast image files (.hdr and .img). I
then did a random effects analysis in SPM99 using those contrast images.
I now want to use SPM2 to use its new PPI (psychophysiological interactions) feature. I know that
old (SPM99) SPM.mat files cannot be used in SPM2. So, I tried designing a new model in SPM2
using the contrast images I had obtained previously. However, this doesn't work. The SPM.mat file
is created, but some fields are missing, such as SPM.xY.RT and SPM.xBF.
Do you know what the problem is? Can it be due to the preprocessing?
Thank you very much in advance for your help. I hope to hear from you soon.
Susana
