Using UNC_neonate template
Hi all,
I am analyzing infants fMRI data (1-6 months) and i need to use UNC template for neonates instead of SPM template. i am using the following pipeline:
• functional Label current functional files as "original data"
• functional Realignment with correction of susceptibility distortion interactions (subject motion estimation and correction)
• functional Center to (0,0,0) coordinates (translation)
• functional Slice timing correction (STC; correction for inter-slice differences in acquisition time)
• functional Outlier detection (ART-based identification of outlier scans for scrubbing)
• structural Center to (0,0,0) coordinates (translation)
• functional Indirect segmentation and MNI-space normalization (coregister functional/structural; structural segmentation & normalization; apply same deformation field to functional)
• functional Label current functional files as "mni-space data"
• functional Smoothing (spatial convolution with Gaussian kernel)
• functional Label current functional files as "smoothed data"
In the settings I used the custom TPM file (the UNC template for neonates). after preprocessing everything looks ok except for the "QA normalization: functional data + outline of MNI TPM template (1)" and "QA normalization: structural data + outline of MNI TPM template (1)" which obviously doesn't match (please see the attachments). This mismatch problem between MNI space and UNC space is continued after Denoising (1st-level). Is there any way to stop transferring to MNI space instead to this in UNC space?
Best,
Parinaz.
