Cutting a EBSD Map

[Camilo Garzón]

Hi,

I need help cutting an EBSD map as people did before in this example

http://mtex-toolbox.github.io/files/doc/EBSDModifyData.html#9

However, when I try to do it, the background disappears and just remains the contour of the polygon.

Could it be an issue of the 5.2 version of MTEX or there is a new way to do this?

Best Regards

Hi!

It works here. Can you confirm that you are using the following code:

mtexdata forsterite

region = [5 2 10 5]*10^3;

close all

plot(ebsd)

rectangle('position',region,'edgecolor','r','linewidth',2)

condition = inpolygon(ebsd,region);

ebsd = ebsd(condition)

figure

plot(ebsd)

If it doesn't work, check also number 2 here: https://groups.google.com/forum/#!topic/mtexmail/adn2k7Vpt70

Hi Filippe,

I did exactly the same procedure and it didn't work.

So, I tried your second suggestion, after that, the MTex didn't plot anymore, so I had to close and open matlab to fix this new issue.

Don't you know another way to cut?

Thanks

Hi! 

If I understood correctly, the first plot is normal and only the cropped one is not showing, right? Is there any error message?

After using 

ebsd=ebsd(condition)

in the above code

what does 

ebsd

return? Is it empty?

Other way of cutting would be to restrict data within given coordinates, e.g.:

mtexdata forsterite

figure; plot(ebsd)

x1=5*10^3;

y1=2*10^3;

x2=15*10^3;

y2=7*10^3;

ebsd=ebsd(ebsd.prop.x>x1 & ebsd.prop.y>y1 & ebsd.prop.x<x2 & ebsd.prop.y<y2)

figure; plot(ebsd)

Best,

Filippe

Hi Filippe,

Thanks for your help again, the second method that you recommend me works to me, however, I was hoping extrapolated this procedure to a grains map; like what I attached; to cut it without having to cut the original EBSD and reprocess the image.

I should be more precise with it before.

Best Regards
