I have been trying to import ArcGIS training sets but am not having any luck. I have a shapefile with five classes, each with a corresonding numeric and text column with class ID. When I import to Taiga, it uses the FID field, which is then not acceptable for the signature file. I tried the database workshop instructions, but that only imports one record for each of the five classes. Suggestions?

Clark Labs Tech Support Team Hello,
After importing your shapefiles into IDRISI you should have a number of files. The .vct (IDRISI vector file) file will contain a sequential numbering of your training sites, and then a .vlx (IDRISI vector link file) file that contains the data that is found in the attribute table of a shapefile.
Assuming that one of your attribute columns contains a numeric value for each training site that corresponds to one of your five classes, you can open up the .vlx file in Database Workshop, click on the numeric column, then right click and select to Export Vector File. This will create a new .vct file that classifies your training sites according to the values in the column that you exported from Database Workshop.
You can create a text legend in the Categories section of the Metadata panel.
