EBSD Data not reading in import wizard

[rahul ravi]

My EBSD data (.osc format) is not taken in by the mtex 4.0.23 tool box. I am using matlab 2014a. Error dialog is showing the message "file not found or EBSD format .OSC does not match data file". The command window shows the message "Exiting txt2mat: file analysis: no numeric data found". I also checked with matlab 2012b and mtex 3.5 as well as matlab 2014a and mtex 3.5. This seems to be working fine in my friends system.

Hi Rahul

There are some issues with *.osc files when you import on MTEX 4 (but used to work fine in MTEX 3.5 as you noticed) because they may have a different structure. I was told by a colleague that Ralf was working on the solution to that. In addtion, if you import an *.osc file, you have to rotate the data according to the rotation below to have the TSL maps and pole figures in accordance with the MTEX maps and pole figures

ebsd = rotate(ebsd,rotation('axis',xvector+yvector,'angle',180*degree),'keepXY')

So it is better to use the *.ang file that you can export via TSL. With this option, you'll ger a message asking wheter you want to use  'convertEuler2Spatial’ or ‘convertSpatial2Euler’ from the ang-import interface. In this case you dont need to do any rotation


I hope it helps

Which version of TSL OIM Data Collection are you using? In my experience, the .osc output from Version 6 works fine with Mtex 3.5, but there appear to have been some changes in format going into Version 7.

In any case, it may be helpful to export your data to the human-readable .ang format using TSL. These types of files can usually be opened in Mtex with relatively few difficulties, although again there seems to have been a format change between v.6 and v.7, and the advantage is that you can open the data file in a text editor to see what is going on. (Notepad++ is much better than the standard Windows notepad for dealing with large text files).

I have written a modified .ang importer that is capable of dealing with some issues that occur in v. 7 of TSL and can supply this if relevant.

Best wishes,
Victoria

I am having a similar problem.  I am using Matlab 2014b and MTex 4.1 beta4 and I'm struggling to import TSL data.  It will not take .osc nor .ang from OIM 6 and .ang from OIM 5.  Is there a trick to uploading .ang files into MTex? 

Thank you for your time!

Yes, attached are the OIM v.5 files.  Thank you!  

[Deborah Shulman]

here is an OIMv6 .ang file as well

Hi Deborah,

thank you for the files. Could you please use MTEX 4.1 and copy the attached files to

mtex/interfaces/loadEBSD_ang.m

mtex/EBSDAnalysis/phaseList.m

With this both files should be imported. This bug fix will be included in MTEX 4.1.1. Thank you for reporting this.

Ralf.
