Yoke on + default colormap

[aghaeifar]

Hi

Is it possible to configure MRIcroGL to launch with the Yoke option enabled by default and use a default colormap other than grayscale?

You can place a script named startup.py in the MRIcroGL script folder (for MacOS, this will be inside the application package, e.g. '/MRIcroGL.app/Contents/Resources/script/startup.py'. This script will be executed when MRIcroGL starts.

import gl
gl.resetdefaults()
gl.loadimage('spm152')
gl.yoke(1)
gl.colorname(0,'magma')

Thanks.
Startup settings are applied correctly when MRIcroGL is launched directly via MRIcroGL.exe. However, when a NIfTI file is opened by double-clicking it (with MRIcroGL set as the default application for .nii files), the startup settings are not applied: the colormap remains grayscale and Yoke is turned off.

I guess I found why it did not work, this issue occurs because of how Windows passes arguments when double-clicking a file to open it.

Workaround:
As a temporary fix, I created a .bat script and set it as the default viewer for .nii files. The script automatically modifies startup.py and launches the file through it.

@echo off

set "NII=%~1"
set "BASE=%~dp0"
set "STARTUP=%BASE%Resources\script\startup.py"
set "TEMP_SCRIPT=%TEMP%\mricrogl_open.py"

copy /y "%STARTUP%" "%TEMP_SCRIPT%" >nul
echo gl.loadimage(r"%NII%") >> "%TEMP_SCRIPT%"
echo gl.colorname(0,'jet') >> "%TEMP_SCRIPT%"

start "" "%BASE%MRIcroGL.exe" "%TEMP_SCRIPT%"
exit

Just to mention, opening file is a bit slower now.
