Dear batch and Matlab experts I set up a batch analysis for a multi-session (4) event-related fMRI study with variable onsets and duration (with 6 condition). The batch runs just fine as long as I only specific one session (for testing purposes). However, as soon as I specify all 4 sessions I keep getting the following error (see below). It has nothing to do with the image file selection since for debugging reasons I was selecting them via the UI. Any ideas what this might be related to? I attached the relevant batch-file but I don't think it's my fault (well, we never know anyway ...) I hope somebody can help since the last two days of my life have been spent on this (I am still young, though) Thx in advance claus SPM2: spm_fMRI_design (v2.34) 11:34:11 - 04/09/2005 ---------------------------------------------------------------- Saving fMRI design : SPM2: spm_fmri_spm_ui (v2.52) 11:34:31 - 04/09/2005 ======================================================================= Mapping files : ...done Calculating globals : ...done Saving SPM configuration : ...SPM.mat saved Design reporting : ???
