Hi Laura,
Can you upload both logfiles to:
http://www.fmrib.ox.ac.uk/cgi-bin/upload.cgi
and let me know the 6-digit reference number?
Many Regards
Matthew

> I am analysing fMRI data from a pyschological study with FEAT on a linux system using the FSL Version 4.1.6. The design includes fieldmaps with B0unwarping.
>
> When running the FEAT analysis with 4.1.6 I got decent results. Then I switched to the 4.1.9 Version of FSL and compared this analysis
> of exactly the subject (same functional-, anatomical scan and fieldmap) using the same designfile (adapted for 4.1.9) to the results of the 4.1.6 analysis.
> In the Logfile for this feat analysis, we get the following error message:
>
> /usr/share/fsl/bin/fslstats FM_UD_fmap -k FM_UD_fmap_mag_brain_mask -P 50
> Mask and image must be the same size
>
> /usr/share/fsl/bin/fslmaths FM_UD_fmap -sub Mask and image must be the same size -mas FM_UD_fmap_mag_brain_mask FM_UD_fmap
> ** ERROR (nifti_image_read): failed to find header file for 'Mask'

> We have tried running this analysis on several different systems (Mac & Debian Linux) and always get the same error message, which doesn't show up on the logfile for the identical analysis using the 4.1.6 Version. We tried comparing the Logfiles for the 4.1.6-Analysis with the 4.1.9-Analysis row by row and it seems to us,
> that with 4.1.9 we are getting a problem with fuge. Several lines are missing, that exist in the 4.1.6 Logfile and the 4.1.9 Analysis
> seems to try and find and fit a "Mask" that the program previously has not created.
> When comparing the designfiles made using 4.1.6 and 4.1.9, we cannot find the point at which this distinction comes into play.

> We are very greatful for any and all hints and suggestions and hope to hear from you soon.
