Just in case someone else runs into this problem with atlasquery's dynamically loaded shared libraries (dyld) on Mac Maverick. I am running Maverick v 10.9.5; XQuartz v 2.7.7; and FSL v 5.0.2.1. The error: % *atlasquery* dyld: Library not loaded: /home/fs0/cowboy/var/jalapeno4_apple-darwin8-gcc4.0/sandboxes/fsl/extras/lib/libz.1.dylib Referenced from: /usr/local/fsl/bin/atlasquery_bin Reason: image not found /usr/local/fsl/bin/atlasquery: line 7: 2693 Trace/BPT trap: 5 ${FSLDIR}/bin/atlasquery_bin "$1" "$2" "$3" "$4" "$5" "$6" "$7" "$8" "$9" "$10" [*] Note that I used Mark Jenkinson's suggestion for a permanent fix, hence the error is referenced from atlasquery_bin called by script atlasquery: https://www.jiscmail.ac.uk/cgi-bin/webadmin?A2=FSL;af2906e1.1107 Previous fixes posted here would not work for me. I don't know why but libz.1.dylib does not exist in ${FSLDIR}/bin/fslview.app/Contents/Frameworks: % *ls -l ${FSLDIR}/bin/fslview.app/Contents/Frameworks | egrep libz.1.dylib* [nothing found] Instead, first I had to find libz.1.dylib on my mac: % *find /usr -name libz.1.dylib* /usr/lib/libz.1.dylib Then I looked at the libraries that atlasquery_bin links to (egrep finds and displays output that contains 'libz'): % *otool -L /usr/local/fsl/bin/atlasquery_bin | egrep libz* /home/fs0/cowboy/var/jalapeno4_apple-darwin8-gcc4.0/sandboxes/fsl/extras/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) /home/fs0/cowboy/var/jalapeno4_apple-darwin8-gcc4.0/sandboxes/fsl/extras/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) I don't have any directory that starts with /home/fs0. I had to change this '/home/fs0' directory to my '/usr/lib' using install_name_tool: % *sudo install_name_tool -change /home/fs0/cowboy/var/jalapeno4_apple-darwin8-gcc4.0/sandboxes/fsl/extras/lib/libz.1.dylib /usr/lib/libz.1.dylib /usr/local/fsl/bin/atlasquery_bin* I had to preface the install_name_tool command with 'sudo' to gain superuser privileges. (Note: this is a long command and should be issued on a single line.) Now atlasquery_bin links to libz in /usr/lib: % *otool -L /usr/local/fsl/bin/atlasquery_bin | egrep libz* /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5) And, hooray!, atlasquery runs successfully: % *atlasquery* *************************************************** The following COMPULSORY options have not been set: -a,--atlas name of atlas to use *************************************************** Part of FSL (build 416) atlasquery (version 1.0) [etc] I hope this helps someone else. At the very least, I'll be able to find this if I need it again. Best, - BettyAnn
