= FSL information = FSL is the FMRIB Software Library. It is a C / C++ / Tcl/Tk package written by the Oxford analysis group. For more information see: * Main page: http://www.fmrib.ox.ac.uk/fsl * FAQ: http://www.fmrib.ox.ac.uk/fslfaq/ * FSL course notes: http://www.fmrib.ox.ac.uk/fslcourse/ You can find the FSL example data set (http://www.fmrib.ox.ac.uk/fsl/feeds/doc/index.html) in `/imaging/local/fsl/feeds`. The data for the FSL course is in `/imaging/local/fsl/fslcourse`. Any problems, report them to MartinMonti. == Using the latest version of FSL == Before running fsl you need to run {{{ fsl_4.1.2_setup }}} which is the latest version of fsl at the moment. By running this command you are also using load sharing with any fsl command. If you want to check if you are using the latest version try {{{ which fsl }}} == Using a specific version of FSL on the CBU systems == If you need to use a specific version, rather than the one pointed to by `/imaging/local/linux/bin/fsl`, then define the path to the version of FSL you want, and put something like this at the end of your `~/.cshrc` file: {{{ # FSL stuff setenv FSLDIR /imaging/local/linux/bin/fsl-4.1.2 source ${FSLDIR}/etc/fslconf/fsl.csh set path = (${FSLDIR}/bin $path) }}} If you want to use the loadsharing system, then replace the last line above with the following: {{{ set path = (${FSLDIR}/bin/loadshare/bin $path) }}} In order for this to work when you login across linux machines, you will (I'm afraid) also need to put the same lines in your `~/.login` file. Put these lines somewhere between the lines `# Space for personal defaults` and `# End space for personal defaults` in the `~/.login` file. By using this method load sharing is not used automatically. == FSL ALIAS suggestions == Occasionally, the FSL GUIs will freeze if you launch them from a terminal with the '&' command and then try to use the terminal. To avoid this problem just add a couple ALIAS commands to your .cshrc file, as follows: {{{#FSL Aliases alias fslview 'xterm -e fslview &' alias fsl 'xterm -e fsl &' }}} (Remember to source the .cshrc file after editing it, by typing 'source ~/.cshrc' in a terminal) Now when you type 'fsl' in a terminal it will open the GUI from a new terminal (if you close the new terminal it will close the GUI, and viceversa). This will allow you to still use the terminal in which you typed 'fsl' without freezing the GUI. If there are other GUIs you use often, just create other alias commands just by teplacing 'guiname' with the command to call the GUI in the following line: {{{ alias guiname 'xterm -e guiname &' }}} == Testing New FSL Versions == FSL has a little tool called FEEDS suite that can be used to run tests on a new FSL installation, to check that all the bits and pieces run smoothly. I [MM] created a small script that allows to run the FEEDS suite by typing one command (I show the help line that is printed if you omit the two arguments): {{{ ./Evaluation_Script_1.csh 'fslversion' 'fslbit' *****USAGE: Evaluation_Script_1.sh 'fslver' 'fslbit' 'fslver' is the FSL version (e.g. fsl-4.1.4) 'fslbit' is the 'bit' version (i.e. 64 or 32) [default 64] }}} The only presupposition of this script is that the version you want to test (fsl-#.#.#) has been unpacked in the following path: /imaging/local/software/fsl/fsl64/fsl-#.#.#/fsl (for the 64 bit) /imaging/local/software/fsl/fsl32/fsl-#.#.#/fsl (for the 32 bit) To test the latest fsl (4.1.4 64bit) you just have to type: {{{ ./Evaluation_Script_1.csh fsl-4.1.4 }}} (The script will warn you that if the second argument is missing it defaults to 64bit) To test the 32bit version, however, you have to specify that: {{{ ./Evaluation_Script_1.csh fsl-4.1.4 32 }}} Once you launch the command it will ask you to check the FSL path and version details before running FEEDS. = Recent Updates: = == 2008/12/15 Installed latest FSL == Type {{{ fsl_4.1.2_setup }}} to use it[RC] == 2008/10/6 small FSL patch requested by Mirjana == Ask her if you're curious [RC] == 2008/9/15 FSL patches applied as requested by Eleftherios == You may now choose between the patched version {{{ fsl_4.1.0_setup }}} and the unpatched one {{{ fsl_4.1.0_nopatches_setup }}} [RC] == 2008/9/1 and 2008/9/2 Installed FSL 4.1.0 == Type {{{ fsl_4.1.0_setup }}} to use it Fixed, added load sharing wrappers, accidentally deleted fsl3.2, hope no-one need it. [RC] == 2008/02/06 Added load balancing to FSL == All FSL 4.0.1 commands are now executed with load balancing. Details... wrote python script /imaging/local/spm/loadshare/runfsl.py which launches an FSL command on the currently least busy machine. Then, /imaging/local/spm/loadshare/fslwrappers.py which makes symbolic links in /imaging/local/linux/bin/fsl-4.01/bin/loadshare/bin This directory is now added by fsl_4.0.1_setup instead of the one with the actual commands in. If you wish to run multiple scripts or jobs in parallel launch with separate xterms like this: {{{ xterm -e [your command 1] & xterm -e [your command 2] & e.g., xterm -e feat myscript.fsf & }}} [RC, MM] == 2007/12/12 Added FSL 4.0.1 == To use, type {{{ fsl_4.0.1_setup }}} at the Linux prompt
