Colorbar scale for Probe Placement Variation

[morrisvanegas]

Although the colorbar in the second figure (Standard Deviation Across Digitized Probes) generated by Tools -> Probe Placement Variability is scaled to the variability of the optodes, the circles don't take advantage of the full color bar.

When attempting to get the colormap [colors = colormap], this results in a 256 row vector. Therefore line 491 in Probe/plotProbePlacementVariation.m should scale to 256, not 64. Scaling to 64 results in the optode colors to be scaled to 1/4th of the color bar, incorrectly indicating that the variability is lower than expected.

Line 491 here:

AtlasViewer/Probe/plotProbePlacementVariation.m

Line 491 in 6c95a97

color = 1+round(63*(p2sd(i)-min(p2sd))/(max(p2sd)-min(p2sd))); % This picks the most appropriate of the 64 colormap colors

Should be replaced with
color = 1+round(255*(p2sd(i)-min(p2sd))/(max(p2sd)-min(p2sd)));

Here, I intentionally added variability on one side of the head when digitizing my modules. The original code (64 based), shows very little variability in the left and right modules, despite the figure 1 (Digitized Probe Positions) clearly showing variability.

When I change Line 491 to scale to 256 (the full size of the color matrix), the colors more effectively demonstrate the increased variability and use the full colormap scale.
