Hi,

I'm looking for some help with an error message that I am getting. I am trying to import some functional data (using batch script) that has been pre-processed in fsl. The data is filtered_func_data_clean.nii as given by fsl, I am then using applywarp to get this data into MNI space using the transform information provided by fsl and naming this filtered_func_data_clean_MNI.nii - this is the functional input data.  All I need to do in conn is to import data, structural segmentation and connectivity analysis (i.e. no extra pre-processing).

I am getting an error each time, but the confusing thing is that when I try to import functional data for 2 or 3 subjects it works fine and completes the analysis. As soon as I try to run it on more subjects the error occurs. I cannot see anything wrong with the data and can't find any info on the error.

The error that I am getting is:

Step 4/7: Importing functional data

Any help would be much appreciated.

Thanks in advance
