error using matlab.graphics.axis.Axes/set

[Brian Greeley]

Hello Andy and fellow ROAST users,

Ran into the Axes issue again (Step 6). I encountered it with my first participant using their T1. However, based on the forum's history and prior sucess I changed the mesh options and added "'meshoptions',struct('distbound',0.5)" and it worked!

However, my next participant I used the same line of code and it failed. Here's my code.

roast('PATH\YA20_WIPVBRAIN_3DT1_0.8mm_20211215120407_21.nii',{'C3',2,'Fp2',-2},'zeropadding',60,'electype','pad','elecsize',[70 50 3],'meshoptions',struct('distbound',0.5))

and I got the same Axes error (see immediately below):

Error using matlab.graphics.axis.Axes/set

Error setting property 'CLim' of class 'Axes':
Value must be a 1x2 vector of numeric type in which the second element is larger than the first and may be Inf

Error in caxis (line 106)
            set(ax,'CLim',arg);

Error in visualizeRes (line 131)
    caxis(dataShowRange);

Error in roast (line 864)
        visualizeRes(subj,subjRasRSPD,T2,node,elem,face,injectCurrent,hdrInfo,uniqueTag,1,vol_all,ef_mag,ef_all);

>> 

Based on another user I updated DP (from 3.2.0 to 3.4.0), updated the library and I still get the same error.

Any help would be most appreciated!

Thanks a bunch,

Brian

Hi Brian,

The general advice I can give to you is that the solver will work when the mesh is of high quality. You can get high-quality mesh by increasing its size. For that you can change the meshing parameter as you already did (also if I remember correctly decreasing distbound will increase mesh size). The other option is to try running this on a Linux machine as it's mostly tested on Linux.

Hope this helps.
