The values string is unchanged in EMBOSS 5.0.0 You need to resolve the
variable (the $(matrixpath) in two places.
In ajax/ajacd.c function acdListPrompt add an extra acdVarResolve call
once "value" has been assigned:
ajStrAssignS(&value, acdAttrValue(thys, "value"));
.. this will resolve the variables for the prompt (if you define
standard: "Y" for matrix)
and the same in acdListValue so the variables are resolved when the user
value is tested.
The same changes are needed for acdSelectPrompt and acdSelectValue if
you use a selection instead of a list.
But there is another way ... in general, we define the path separately
as ACD type "directory" if we allow the user to change it, or hard code
it and use a Unix environment variable if the user needs to customize it. In
your case you obviously have a fixed path, but it has to be hardcoded
somewhere because what is passed to the application is the string "Human".
One more change ... with a long "short value" like "Arabidopsis" the
printed list looks untidy. For the next release we can test for the
longest name and adjust the margin.
Hope that helps
