Hello,
 If this is still an issue, can you confirm the files are blank with ( e.g. ) fslstats -r -R?

Kind regards

Hi All,

After running ICA Aroma and regressing out CSF and white matter, I applied a bandpass filter using the following command:

fslmaths $OUTPUT/denoise_residual_nocsfwm.nii.gz -bptf 25.0 -1 -add $ICADIR/timeMean.nii.gz $ICADIR/final_denoised_func_data.nii.gz

This worked for most of my 150+ runs; however, about 15 of them failed. When I viewed these output files in fslview they just showed an empty grey box. The denoise_residual_nocsfwm.nii.gz and timeMean.nii.gz files appear to be fine, so I'm not sure where this is going wrong. I also tried running this directly from the command line for one participant (rather than as a batch script), but that still did not work. Any suggestions would be appreciated!

Thanks,
Rachel
