I've been fiddling around for a week trying to figure this out so I'm hoping you can help!\r\n\r\nI have a data set that is restricted to the occipital lobe. It's an angle map, so the values range from 0-360, with 0 as a meaningful data point.\r\n\r\nWhen I load the data in webshow, the rest of the brain shows as whatever color is set at below the minimum point in the colormap. So if I use the J4R colormap, the rest of the brain is colored in yellow. \r\nI tried making all the values NaN, but it still colors it as the minimum value.\r\n\r\nAlso, within the data itself, I've excluded some voxels that didn't meet an inclusion threshold. I set those voxels to be NaN as well, however they appear colored as a 0 voxel instead of blank or the grey background color.\r\n\r\nSo is there a way to change this? Perhaps an option when I'm loading the data that I'm missing?\r\n\r\nI hope this make sense!\r\nThanks,\r\nMaggie"},"comment":{"url":"https://api.github.com/repos/gallantlab/pycortex/issues/comments/220398248","html_url":"https://github.com/gallantlab/pycortex/issues/151#issuecomment-220398248","issue_url":"https://api.github.com/repos/gallantlab/pycortex/issues/151","id":220398248,"user":{"login":"alexhuth","id":5116984,"avatar_url":"https://avatars.githubusercontent.com/u/5116984?v=3","gravatar_id":"","url":"https://api.github.com/users/alexhuth","html_url":"https://github.com/alexhuth","followers_url":"https://api.github.com/users/alexhuth/followers","following_url":"https://api.github.com/users/alexhuth/following{/other_user}","gists_url":"https://api.github.com/users/alexhuth/gists{/gist_id}","starred_url":"https://api.github.com/users/alexhuth/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/alexhuth/subscriptions","organizations_url":"https://api.github.com/users/alexhuth/orgs","repos_url":"https://api.github.com/users/alexhuth/repos","events_url":"https://api.github.com/users/alexhuth/events{/privacy}","received_events_url":"https://api.github.com/users/alexhuth/received_events","type":"User","site_admin":false},"created_at":"2016-05-19T17:39:36Z","updated_at":"2016-05-19T17:39:36Z","body":"Ahah! Great! Well, actually, maybe annoying for you, but at least the problem isn't on our end ;). I'm gonna close this issue. But let us know how you fix this!"}}
