Dear Alfonso,

I am using the latest version of CONN (18b) and want to do field mapping correction with resting state data. Data were acquired on a Siemens scanner and I have one phase diff and two magnitude images. I have imported the images together with the functional images in the conn gui (see screenshot). I have tried to run preprocessing importing the short echo magnitude and phase images only (together with the resting state file) and importing the two magnitude and phase images (together with the resting state file). I have also tried "Fieldmap type: automatically detect" and "Fieldmap type:magnitude, phase diff files." Finally. I have tried to import all the files in the different orders; i.e., fmri, mag1, mag2, phase and mag1, mag2, phase, fmri.

This is the error I am getting when trying any of the above (reported in previous posts):






One thing is that I can only import the field map images when the primary dataset is selected in functional.setup. When I change to secondary dataset #2 (fmap), there is no option to import data, and I wonder if this has anything to do with the issue.

Finally, I also tried using the patch you provided in your previous reply in this thread, but got the same error message.

Thanks for your help with this.

Best,

Juan
