Error: /undefined in A

Hi everyone. I’m trying to plot a map in ISOLA Software with GhostScript. However I’m getting this error “Error: /undefined in A” and I could not find the reason. I’m adding a screenshot for full error. What should I do?

Apparently ISOLA is some software that uses GMT to make plots. Unless we know what commands were actually issues and what version of GMT etc etc was used it is not possible to know what is happening. Perhaps ISOLA has a GMT 4 requirement and you are using GMT > 4?

ISOLA used to support GMT4 only, but not anymore. The new version supports v.5 and 6 see here GMT version needs to be specified at the isolcfg.isl file. In order to troubleshoot locate the batch file that creates the problem, run by hand and check for errors.
