After a bit of massaging, I got v1.7.0 to compile on Mac OS X Tiger and it runs under the X windows port. (I see that there is a version that should run with Aqua, but that's another question for another time.) I see by the announcements link on the SourceForge page that this version should read Solexa traces. I see only the usual file types, though. Can anybody confirm that this version should read Solexa traces, and can you offer any tips how to read them in?
