SNOB - A SNOMED Browser
FAQ
The log file contains the following remark(s):
A membership file must contain ALL members of ONE subset.
This is a known issue. SNOB expects to find ALL members of ONE subset in a membership file. This is because SNOB builds a navigational structure on the imported subsets, which allows you to drag a subset from the subsets window to the browser pane.
If you have a membership file that contains the members of two or more subsets, you should split this membership file into two or more files, each containing just the members of one subset before importing the subset into SNOB.
