Hi Pieter, Thanks very much for taking the time to provide the advice and explanations - very helpful! As you suggested, my search path was not defined properly to locate gnuplot. If I typed "gnuplot" in the Terminal, I would get the message, "command not found". Now, Gnuplot is in /usr/local/bin and this directory is listed when I type "echo $PATH". Now when I type "gnuplot" in the terminal, I get: $ gnuplot G N U P L O T Version 4.4 patchlevel 3 last modified March 2011 System: Darwin 10.7.0 Copyright (C) 1986-1993, 1998, 2004, 2007-2010 Thomas Williams, Colin Kelley and many others gnuplot home: http://www.gnuplot.info faq, bugs, etc: type "help seeking-assistance" immediate help: type "help" plot window: hit 'h' Terminal type set to 'aqua' gnuplot> When I start up Galaxy, and try to run the Boxplot tool, I now get a different error: An error occurred running this job: gnuplot> set term png size 2048,768 ^ line 0: unknown or ambiguous terminal type; type just 'set terminal' for a list gnuplot> plot '/Users/JJWhyte/galaxy-dist/database/files/000/dataset_6.dat' using 1:7:11:12:9 with candlest I think this is related to the environment, as you explained in your second paragraph. I tried starting gnuplot from the Terminal first, then typing "set term xterm", and then exiting, but this didn't change the error. Could you please explain how you set the environment in the galaxy/run.sh script? Again, I appreciate the help.

What happens if you type gnuplot in a Terminal window yourself? If you also get "command not found". There is either still something missing or your environment is not setup properly. If the tool works if you execute it yourself in the Terminal, but it fails in Galaxy, you do have all the dependencies and it's clearly an environment setup issue: your OS will search for the binaries in a search path defined by the $PATH environment variable. This means that if you call "gnuplot" without specifying the path where it is installed, the OS will look in all directories specified in $PATH to find it. If it cannot find it, it will give you "command not found". Additionally you may have to set $LD_LIBRARY_PATH as well if the installed tools link to libraries installed outside "default" locations. Hence if you go to the Terminal and type: echo $PATH You will see a colon separated list of directories that should include the location where the gnuplot binary is installed. If this is not the case, please Google for setting $PATH on Mac OS X. If gnuplot does work if you execute it on the commandline, but it fails in Galaxy, it most likely means the environment for the user used to run Galaxy is different from yours (and the location where gnuplot is installed is missing from $PATH). In that case you can either set the environment in the galaxy/run.sh script used to start Galaxy or if you can call a bashrc script to set the environment from galaxy/run.sh. I use the latter where I have one bashrc script that sets the environment for all users and by calling this one from galaxy/run.sh I make sure the environment for Galaxy is exactly the same as for my (command line) users.

The instructions on the GetGalaxy wiki are clear, and I was able to download and install from the anonymous Mercurial repository. Galaxy starts up and runs just fine for tools like "Get Data", "FASTQ Groomer", and "FASTQ Summary Statistics". The problems started when I try to run Graph/Data Display -> Boxplot (GnuPlot). I get the error: "An error occurred running this job:/bin/sh: gnuplot: command not found Error running gnuplot." The FASTX Barcode Splitter also gives me an error: "An error occurred running this job:/Users/Me/galaxy-dist/tools/fastx_toolkit/fastx_barcode_splitter_galaxy_wrapper.sh: line 65: fastx_barcode_splitter.pl: command not found zcat: /Users/Me/galaxy-dist/database/files/000/dataset_10.dat.Z: No such file or directory sed: illegal opt" I'm assuming these are Tool Dependency problems, although I have tried to install the OS X versions of GnuPlot and the FASTX Toolkit and still get errors. Are there any suggestions from users who are successfully running Galaxy on OS X?
