Set default interpolation of webgl server

[Gilles86]

Hi,

I'm a big fan of PyCortex and used it at lot for a 7T fMRI data set we collected, visualizing ocular dominance columns.

You can see some results for example here:
http://aeneas.labs.vu.nl/odc/sub-06/

I want to include these renderings as supplemental material to the paper. However, I think the rendering looks much better when it uses "trilinear" interpolation, instead of nearest neighbor interpolation. Is there a way to make this the default interpolation when you make the static webpage using cortex.webgl.make_static?

Cheers,
Gilles

@alexhuth, I remember we talked about similar issues at some point, any ideas? Thanks!

Hey folks -- so afaik there's no config setting for this, but you should be able to control it programmatically. That means you could add a line to your template HTML file that sets the sampler as soon as the brain is loaded (i.e. in the onload event). It should look something like this:
viewer.ui.set("surface.{subject}.sampler", "trilinear")
where {subject} is replaced by your subject identifier.

This works for me on a test viewer, but unfortunately doesn't seem to work on the viewer @Gilles86 linked because your subject identifier (odc.tr) has a period in it, and dat.gui uses periods as separators. There might be a workaround for this, but in the meantime I'd recommend either using a different subject identifier or setting the parameter anonymize=True when you call cortex.webgl.make_static, which should change the subject identifier to "S1".
