Dear Sir, I will look into the suggestions, i would like to highlight one important aspect, I do not have field map acquisition files , for this reason i did not provide any file path for variable "MagnitudeInputName" in SeimensFieldMapProcessingAll.sh, Can i possibly comment out the necessary sections of code to avoid generating Magnitude_brain and Magnitude_brain_mask images
