In this case you need to run catps2ps -m -i to remove unsupported commands from the Postscript file.ĭownload and open the installation package ( HYSPLIT_mac.dmg) and then run the Install_hysplit.app. Use Preview, however, if there are too many Postscript frames in a file, Preview may have trouble converting the output to a viewable PDF. Go to the ImageMagick web site to download the most recent Mac version. ImageMagick can then be used to convert these files to unsupported formats. However, on MAC systems Ghostscript is not required because the Preview function can be used to export the Postscript file to a select number of other formats. The capability to convert the Postscript graphics to other graphical formats is enabled within the GUI through ImageMagick, which normally requires the prior installation of Ghostscript. Install the software to the suggested default directory prior to installing HYSPLIT. If not already installed, you can download Tcl/Tk from the Tcl/Tk web site. Most Unix / Linux operating system distributions, as well as Mac OS X, include Tcl/Tk. The HYSPLIT installation includes all the GUI scripts, but the Tcl/Tk interpreter is not part of the distribution. However, it is easier for novice users to use the Tcl/Tk interface. The model can also be run using a command line interface. Depending upon how the LINUX scripts are copied to a Mac, you may need to correct the EOL character using the Mac equivalent of dos2unix.Īlthough not required to run HYSPLIT, a GUI composed of multiple Tcl/Tk scripts is provided with HYSPLIT. The other option is to replace gs with the open command. However, if you are running the LINUX scripts in a terminal window, the gs display command will fail unless ghostscript has been installed. The HYSPLIT Mac installation is similar to a Windows PC except that the Mac OS supports the native display of Postscript files, therefore Ghostscript is not required.
