I'm trying to run my analyses on a machine with faster hardware, but this means switching from a full Matlab 2013a license to a Matlab home license (R2015b). In both cases I'm running Windows 7 (pro). The Matlab home license has the following toolboxes installed: curve fitting, signal processing, statistics and machine learning, and wavelet. Is there another toolbox needed? I have a script that previously ran fine with fieldtrip version 20140316. Now it won't run at all with that version. I have better luck with version 20160123, but I still run into the problems below. The script seems to get all the way through a call to ft_freqanalysis, but then hangs indefinitely, never moving on the next command, returning to the command prompt, or generating any error message. Also, the following error appears if I call on ft_singleplotTFR: Undefined function or variable 'rgb2hsv'. Error in ft_plot_matrix (line 237) hsvcdat = rgb2hsv(rgbcdat); Error in ft_singleplotTFR (line 463) ft_plot_matrix(xvector, yvector, datamatrix, 'clim',[zmin,zmax],'tag','cip','highlightstyle',cfg.maskstyle,'highlight', mask)

Hi Jen, On you can find the requirements. In principle your new platform sounds ok to me, although I don't know the differences between the home, academic and other versions. Ah, searching my own laptop for the file you mention I see that a copy is here /Applications/ which means that it is in the image processing toolbox. >> help images Image Processing Toolbox Version 8.1 (R2012b) 20-Jul-2012 But there are also copies here /Applications/ /Applications/ /Applications/ /Applications/ /Applications/ so it seems that it is not unique to the image processing toolbox. But my MATLAB installation is using the one from images: >> which rgb2hsv.m /Applications/ and you lack that toolbox.

since we don't want to rely on math works toolboxes too much (also for in house use, since we have a limited number of toolbox licenses), I looked for a drop-in replacement. We have more of those drop-in replacement functions and keep them in external/stats, external/signal. I now made an exteral/images and implemented a rgb2hsv replacement function. mac011> svn commit Adding images Adding images/README Adding images/rgb2hsv.m Sending stats/README Transmitting file data ... Committed revision 11124. It will be in the next release. You can download it from and save it somewhere on your path. I only tested some simple use cases (comparing to the math works version output), but not extensively. Please let me know if you encounter problems with it.

Hereby I am closing multiple bugs that have been resolved for some time now. If you don't agree to the resolution, please reopen.
