  • Comment: Projection Activity errors for mousing

    Thanks, Chris, for fixing that! However, there is still a problem: The label on the Projection Activity plot is now incorrect; maybe fixing that long ago led to this problem. E.g. in tiny.ty, the Projection Activity window says "Afferent (from V1)", when it's really from Retina.

  • Comment: TwoRectangles aspect_ratio

    Thanks! Fixed in revision 10666. Feel free to fix obvious bugs like that yourself; if you want to do that, then I'll add you as a Topographica developer.

  • Followup: RE: saving/restoring connections

    Hi Alessio, I don't think the situation you describe has come up for any of us yet, so we haven't documented it anywhere, but I think it should already be possible to do whatever you want in this case, withough having to mess with the internal weights inside any object. The save_snapshot and load_snapshot commands are based on Python's pickle support, and simply call pickle on a data...

  • Projection Activity errors for mousing

    The Projection Activity window appears to be broken, perhaps something to do with the changes to display errors in individual windows and/or fixing coordinates to display in more windows. In r10628, if one starts tiny.ty and opens a Projection Activity window: ./topographica -g examples/tiny.ty -c "topo.guimain['Plots']['ProjectionActivity']()" then there is an IndexError whenever the...

  • Followup: RE: problem compiling matplotlib on Fedora 11

    We've upgraded the SVN version of Topographica to use matplotlib-0.99.1.1, which indeed does include the fix you mentioned above, and also works fine with 3D plotting again. Your fix is still necessary for the 0.9.6 release, but we'll make a new release later this year that will use the new matplotlib version instead. Thanks for the bug report!

  • Real-world units in GUI, scripts

    Right now, everything in Topographica's user interface is based on a single standard type of unit, e.g. Sheet coordinates for distances on Sheets. This makes everything consistent, but many people will want to use a real-world unit such as millimeters (for a cortical area), or degrees of visual angle (for the retina). It would also be extremely helpful to be able to use multiple such...
