    Hi! I have a question. I have two BOLD runs of resting-state fMRI data for the same subject, and I want to combine them into a single BOLD run. I’ve tried using FSL’s fslmerge by time, but it doesn’t seem like the best approach. Would it be advisable to combine the two BOLD runs before preprocessing? If so, what would be the best method to do this?

    This is helping me a lot! One thing to ask is that, I co-registered my T1 to EPI image, unlike what you did (EPI to T1). So, I thought my deformation file contains information transforming T1 to EPI. If that's the case, how is it used for normalization? Since, normalization warps EPI to MNI, isn't the deformation info. for T1 to EPI unnecessary?

    • @pratikian
      @pratikian 5 місяців тому

      Hey, I am glad this helped you. TO answer your question, the co-registeration does not create the deformation field. Segmentation creates the deformation field. Since segmentation is always done on the anatomical image, the defomation field is always from anatomical space to MNI space, hence co-registeration of the EPI and anatomical T1 image is important. Hope this answers your question.
