Dear all, 

In CONN version 18b, there is an option to correct for field mapping. However, I want to make sure that I understood well this option:

1- So my output from the scanner are two nii files, I assume one is the phase and the other is the magnitude image. Should I merge them and load this 4D image? If yes, can I use the fslmerge or there are other better options?

2- Should I create vdm file in spm before or I just load the magnitude and phase images, and CONN automatically creates vdm?

3- where should I load these images, as far as I understood, I load them in the secondary data set, right?

Thank you so much for the help!
