The t-test plugin was re-written for RKWard 0.6.0. Version 0.5.7 had the more limited dialog labelled "Two-variable t-test". So this is not a cross-platform difference, but a cross-version difference(*). > This is on both versions 0.5.7 and 0.6. For 0.5.7, the more limited dialog is what you'd expect to see. If you see this with version 0.6.0 - on any platform - this will be due to left-overs from a previous installation. I'd be rather surprised so see this happening on Linux (can you second-check that one, please?), but in fact, on Windows it's rather easy to get into such a situation, if you upgrade RKWard, without removing the previous installation. Hm, I'll have to think about a good way to prevent this. Anyway, to fix this (in RKWard 0.6.0), go to Settings->Configure RKWard- >Plugins, Remove C:\Old\Installation\Path\share\apps\rkward\all.pluginmap (typically the topmost, or only entry), and add C:\New\Installation\Path\share\apps\rkward\all.pluginmap instead. > Very few people at my university use anything other than Macs, so it's not > much of a problem, but it does mean that the 2 Windows users in class can't > do the one-sample analyses... While at it, a totally different matter: AFAICS, you added advice to our wiki to run RKWard as Administrator on Windows. Could you give some background info on what goes wrong, otherwise? Could it be the same issue as discussed, here: http://www.mail-archive.com/rkward-devel@lists.sourceforge.net/msg01933.html i.e. crash, if you are inside your own home directory when opening a file dialog for the first time? Regards Thomas (*) On the Mac, prior to RKWard 0.6.0, only development versions were available. I'd have to go hunting for the exact timeline, but probably you've always seen the new variant on the Mac, for this reason, even long before RKWard 0.6.0 was released.
