"Load" vertstats file as surface label? #67

Closed gdevenyi closed 5 years ago

gdevenyi commented 7 years ago

I have a vertstats file I'd like to use a "label" set, rather than a continuous statistics set.

Loading it with the regular method doesn't look nice, as the labels cover a wide range and don't map nicely to a continuous display.

Display now has manual "surface segmentation", is there a possibility of loading a verstats file as a surface segmentation rather than as statistics?

@gdevenyi So like the volumetric labels, integer values (I hope they are integers) on the vertices would map to specific colours, rather than a continuous colour map?

Correct

@gdevenyi This is now possible with GIFTI "label" files, as they can contain colour map information. Can you give me an example of a vertstats file that would have this type of data? I'm curious to see what, if any, metadata is present. Otherwise I can just have a special case that uses a discrete colour map if integer data is detected.

The AAL, DKT, lobe maps from CIVET.

Using this and generally it looks great, one issue, the value "0" should probably be treated special.

Right now, it gets considered and assigned a colour, I think it should probably be the object base colour.
