Missing plugin for Color MIP search

[mmc46]

I tried to use https://github.com/JaneliaSciComp/ColorMIP_Mask_Search/tree/master/ColorDepthMIP_Generator

to generate a MIP image from an 8-bit JFRC2010 registered stack. But not long after I start the macro, I get an error:
"Plugin or class not found: "8bit_Gray_Clip_plugins.Mask_Brighness_Measure"
(java.lang.ClassNotFoundException: 8bit_Gray_Clip_plugins.Mask_Brighness_Measure)"

I'm using Fiji version: 2.0.0-rc-67/1.52d.
Automatic Brightness adjustment ticked, DSLT version:line

Could you suggest a fix please?

Hi Marta,

Could you send me your sample data? My email is otsunah@janelia.hhmi.org
The code has been adjusted for the 12bit data. Could be some issue with the 8bit less GAL4 expressed data.

Best,
Hideo
