<DIV>Hi Jinsong, </DIV>
<DIV> </DIV>
<DIV>I've been trying to do the same thing. Actually I wrote the activation cluster from the fMRI model to an image file. There is an option to export the activated cluster (ROIs) in ANALYZE format. Once it is in this format it can be read by ROIeditor/DTIstudio. </DIV>

<DIV>I am able to import these ROIs from an fMRI activation map onto DTIstudio...but..I am having problems understanding if the orientations are correct. As per SPM (which follows neurological format) we had an activated cluster only in the left side of the brain. I saved this cluster out in ANALYZE format to be read out by DTIstudio. (My understanding is that DTIstudio follows radiological convention by default and hence it automatically does the R/L flip for display but does not make any changes to the header file.) Since my cluster is on the left and the format is in ANALYZE....I expected DTIstudio to make a flip and give me the cluster on the right side of the brain (which is the left side in neurological convention)...but it still pops up on the left. Hence I am not sure if there is a problem while saving out the files as ANALYZE in SPM or while reading it in DTIstudio. It would be great if you could help me solve this issue. </DIV>

<DIV>Many thanks, </DIV>
