Thank you very much for the advice. I had our version of AfNI updated to the newest version and am still having the same problem. I contacted the IT department that handles these issues and had him check the binaries and he said the following: there does not appear to be a binary named 3dSkullStrip. Would it be under a different name? If anything he said that he could install the binary: assuming it was compiled under a compatible version of Solaris and we have all of the dynamic libraries installed that it likely links to. Would I be able to get these files and just have him install them directly to fix the problem I have been having with 3dSkullStrip?
