No support for long keywords
The CXC datamodel has support for long - i.e. longer than eight character - keywords using a combination of standard DSTYP/DSVAL keywords. These keywords do not show up in the Header Keywords section of the prism gui.
Missing or corrupted column information
Some Linux distributions use GTK themes which are incompatible with the version of GTK shipped with CIAO. This can results in some elements of the GUI not rendering correctly. Often this will cause the header row with the column names to be either missing entirely or appear corrupted (overlapping text).
Users can work around the incompatibility by setting the GTK_THEME environment variable.
bash$ export GTK_THEME=Default or tcsh% setenv GTK_THEME Default
Prism hangs with bad file selection
Trying to load an incompatible data file in prism causes the GUI to hang, requiring killing prism to exit.
Segmentation fault when trying to launch prism
The prism GUI will segmentation fault if there are incompatible .fontconfig files cached on the user's system. Try renaming (or removing) the .fontconfig cache:
unix% mv ~/.fontconfig ~/.fontconfig_orig
If this does not fix the prism problem, contact CXC Helpdesk.
The name of files in the tab does not account for "/" in DM filters.
Some DM filters include the "/" character, for example when using various ASCII file format: "mytab.tsv[opt kernel=text/tsv]". Prism only recognizes the "/" as being part of the path and only displays the text after the final "/" in the tab header.
