Hi Alfonso.  We segmented the anatomical files of several subjects in Conn, but when we were uploading a CSF file for one of the subjects, we noticed that the segmentation looked unusual, with much of the of area usually segmented as CSF missing and showing up as black.  (At first we thought there was a problem with the file loading, but we realized later that the file actually loaded ok as there were some small blips of CSF in a few areas.)  Please see the attached jpg file, CSF_displayInCONN.jpg.  The file looks similar when displaying in SPM8.  Since the file looks very different from that of the other subjects, it seems we probably shouldn't use it, but we were wondering what happened and what we could do to obtain a good CSF segmentation.
 
We searched through the help forum in NITRC and we are very sorry if we missed anything.
 
Thank you very much for your help!
