Video Tutorial on registration anatomical and layer-fMRI data with ITK-SNAP and ANTS

[@侯元昊]

hi Can a Tmax color map be registered to DWI?

[@hemahema3788]

Hi Ants Experts, Many thanks for this useful tutorial. I wonder if you recommend any similar way for template generation step by step. Many Thanks in advance

Thanks! Do you know of a way to undo a change during manual registration? I am currently using this tool to manually register a T1 and a functional image and I have to restart if I make a mistake without noting the previous parameters.

Thank you for this video. I am wondering why in 7T I often see people co-registering from the T1 to the EPI? and not the other way around as it's often done (which seems more intuitive ). I imagine this has to do with not changing the EPI image, but I am not sure here whether advantages are more than the cons; Can you please comment here please? :) Many thanks

Panagiotis. The reason, why high-resolution fMRI studies usually register the anatomy to EPI and not the other way around is to keep the functional data as unaffected as possible. every spatial alignment comes along with a spatial interpolation step, which ultimately blurs the signal. See this paper for more info (e.g. Fig. 1): dx.doi.org/10.1016/j.neuroimage.2017.04.053 This is usually not a bit issue in conventional fMRI, where the signal is blurred anyway.

Thank you very much indeed. This video helped me very much. Could you please tell me how can I run that script? I mean I do not know by which software I can run Registration.sh

[@layerfmri]

Hi tayebeh, Sure, the Registration.sh is part of ANTS github.com/ANTsX/ANTs. I tried to explain how to use it here: layerfmri.com/2019/02/11/high-quality-registration/ I hope that helps.

Thanks again. I want to register two structural T1-W images. I have used your script and performed exactly like what you have explained in this tutorial video. but I got an error: transform file does not exist: registered1_0GenericAffine.mat Could you please help me to fix this error?
