Error during preprocessing
Hello, I am trying to run my anatomical and
functional images through the default preprocessing pipeline, but I
keep getting this error message:

It seems to run for a few more iterations and
then it says:

Job execution failed. The full log of this

Can anyone help me out with this issue? Thanks
so much!

RE: Error during preprocessing
Hi Nadiak,
This may indicate that your original functional files have some unexpected dimensionality (either it is not really a BOLD acquisition file or it may be somehow corrupted). Could you please check in the Setup.functionals tab your current functional files, hover over them and let me know their dimensions? (e.g. it should look something like the attached example screenshot, where the dimensions are 72x72x47 voxels and 119 timepoints)
Thanks
Alfonso
