Plotting ODF sections with sample symmetry

[Jay Einhorn]

Hello,

I'm trying to plot phi2 sections of an ODF computed in MTEX with 5 degree resolution. The data comes from pole figures exported from MAUD and loaded into MTEX via the BEARTEX interface (.xpe extension pole figure files). PlotPDF works fine for recalculated pole figures, but I would like to plot phi2 sections of the ODF at 5 degree phi2 resolution.

What's strange to me is that it works when I do not specify sample symmetry (i.e. '1' or triclinic) but when I specify orthotropic ('222'), it will only let me plot at most 6 sections. If I try to do more it gives me an empty plot, albeit with the appropriate angles ranges (phi1 and Phi 0 to 90, see attached). Is there a reason why the number of phi2 sections would be limited?

I've tried both of the following, to no avail:

phi2sections=[0,5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85]*degree;

plot(odf,'phi2',phi2sections)

and

plot(odf1,'phi2','sections',18)

However, the following does work:

plot(odf1,'phi2','sections',6)

There are no error messages in either case, just the empty plot in the former and a full plot (i.e. it works) in the latter. I'm running MATLAB R2014a for Windows and MTEX version 4.3.2. Any advice would be greatly appreciated.

Thanks so much,

Jay

Hi,

I think you should try plotSection(odf, 'phi2', [0, 40,45,60,90]*degree)

Hope this works.

Best Regards,

Suresh

Hi Jay,

I can not reproduce this. I do not really have an idea what is going wrong. Maybe

1. graphics, try set(gcf,'renderer','zBuffer') 

2. memory issues, try less sections

May be you can tell at which number of sections it breaks.

Ralf.

Hi all,

Thanks for the help. It must've been memory issues, as I got it working by importing less pole figures.

Thanks,
Jay
