cifti vis requires workbench 1.2.3 and image magik to function properly.. When these are not loaded, it produces user-unfriendly errors.

Solution, add extra dependancy checks directly into the program..and user-friendly error reporting

Might consider doing this for all of the functions..

image magik is no longer a dependency

dunno about workbench 1.2.3 checks
