Dear Alfonso,

I am trying to do the pre-processing with MRI data acquired from a Phillips scanner. We had our EPI rsMRI data and a reverse phase acquisition.

I have the fieldmaps calculated from topup (FSL) and I uploaded it as a secondary file in CONN (labeled 'fmap'), and I also indicate that it is a pre-computed fieldmap file (in Hz) but I receive this message:


ERROR DESCRIPTION:

I also get this: Warning: unable to find TotalReadoutTime or BandwidthPerPixelPhaseEncode information


I looked at the json file, and this information is not there (at least not under these terms). Maybe I could enter manually the Total Readout Time? If so, how I could find/calculate this info?


What could be the problem?

Thank you very much in advance,

Geraldine Rodriguez Nieto.
