I am very new to the software and have just begun assessing Talairach outputs for my subjects. I am confused in that I cannot seem to find a balance I am happy with between positioning of the green lines in both the horizontal and sagittal views for multiple subjects. I opened the talairach output with the following command (tkregister2 --mgz --s SUBJID --fstal --surf orig) and everything looked perfectly aligned for all the subjects I have tried in both the coronal and sagittal views but in the horizontal view the green lines went well off the back of the brain. I have attached a screenshot. I tried to translate the brain but that did not seem to solve my issue and I realized I needed to scale the length of the brain. When I did that I was more pleased with the outcome but the corpus callosum did not match up nearly as well after I did that (second attached screenshot) and that was the primary landmark I was using to pass my images in terms of talairach output assessment. Do you have any advice for me?
