function [odf,alpha] = calcODF(pf,varargin)
% PDF to ODF inversion
%
% *calcODF* is one of the main function of the MTEX toolbox.
% It estimates an ODF from given Polefigure intensities by
% <PoleFigure2odf.html fitting an ODF that consists of a large number of unimodal ODFs to the data>.
% It does so by minimizing a least squares functional. The command
% *calcODF* supports <ghost_demo.html automatic ghost correction> and
% <dubna_demo.html the zero range method>.
% The function *calcODF* has several options to control convergence,
% resolution, smoothing, etc. See below for a complete description.
%
% Syntax
%
%   odf = calcODF(pf)
%   odf = calcODF(pf,'halfwidth',5*degree)
%   odf = calcODF(pf,'ZERO_RANGE')
%   odf = calcODF(pf,'resolution',2.5*degree)
% 
% Input
%  pf - @PoleFigure
%
% Options
%  KERNEL            - the ansatz functions (default = de la Vallee Poussin)
%  KERNELWIDTH | HALFWIDTH - halfwidth of the ansatz functions (default = 2/3 * resolution)
%  RESOLUTION        - localization grid for the ansatz fucntions (default = 3/2 resolution(pf))
%  BANDWIDTH         - bandwidth of the ansatz functions (default = max)
%  ITER_MAX          - maximum number of iterations (default = 11)
%  ITER_MIN          - minimum number of iterations (default = 5)
%  REGULARIZATION    - weighting coefficient lambda (default = 0)
%  ODF_SAVE          - save ODF simultanously
%  C0                - initial guess (default = [1 1 1 1 ... 1])
%
% Flags
%  ZERO_RANGE        - apply zero range method (default = )
%  NOGHOSTCORRECTION - omit ghost correction
%  ENSURE_DESCENT - stop iteration whenever no procress if observed
%  FORCE_ITER_MAX - allway go until ITER_MAX
%  RP_VALUES      - calculate RP values during iteration
%  ODF_TEST       - for testing only
%  SILENT         - no output
%
% Output
%  odf    - reconstructed @ODF
%  alpha  - scaling factors, calculated during reconstruction

Hi Rüdiger,

Are you asking for the above file?

Thanks

[zmichels]

Did you install from the repository? ... or instead from the downloads page here: http://mtex-toolbox.github.io/download.html

The problem you have shared is similar to ones people have had when they did not install from the downloads page. The downloads on the download page have some necessary compiled portions of the toolbox that are not pre-compiled in the repository folder.

Perhaps you have already tried to install from the files on the downloads page... But if not, I would give that a go first to see if it helps.

Best, Zach

Hi RH, The issue is only for one sample condition (i didn't know why), but for the other sample it is working fine. Thanks.

Have you put the mtex folder in your Matlab folder? If not, you might try that, too. I think on some computers or systems it needs to be located there.

Thank you for the suggestion. I get the same error with MTEX installed in matlabroot (C:\Program Files\MATLAB\R2014b\mtex-4.3.1), as well as in my MATLAB user folder (C:\Users\wlepage\Documents\MATLAB\mtex-4.3.1). Any other ideas?

[ralfHielscher]

To everybody with problems running the precompiled binaries. Could you please post the log file? You get the name of the log file from

getMTEXpref('logfile')

Please do also indicate, which version of Windows, Matlab and MTEX you are using.

I'm very sorry for your inconvenience and hope we can fix the issue soon.

Ralf.

[wlepage]

I'm running: Windows 7, 64 bit MTEX 4.3.1 Matlab R2014b

Unfortunately there is no log file at the location given by getMTEXpref('logfile'), only the log file from the error (pf2odf34896.txt that I included previously).

[wlepage]

Also, I tried check_mtex, but that seems to show no problems. I would eagerly welcome any further ideas on this.

Hi there,

Issue with: pf2odf.exe could be solved if you change this on *.m file

% create a Pole Figure variable containing the data pdf **= loadPoleFigure(fname,h,CS,SS,'interface','uxd');

% defocussing pf_def = loadPoleFigure(fname_def,h,CS,SS,'interface','uxd');

% correct data pf = correct(pdf,'def',pf_def);

Thanks,

[ralfHielscher]

Hi wlepage,

I'm very surprised that check_mtex works but odf reconstruction of your sample does not work.

Could you please run (section be section) the demo

edit PF2ODFAmbiguity.m

and tell me weather the odf reconstruction works there.

If its only you example that does not work, please try to send your data and your script.

I'm very sorry about your inconvenience.

Ralf.

[0309akash]

Hi, I went through the above thread and still unable to resolve this issue. I am also facing same problem for ODF calculation. Does anyone has solution yet? I tried with both mtex 4.2.1 and 4.0.23. Here are error files.

Akash

[ralfHielscher]

Akash, could you please run in a terminal

ldd --version

[0309akash]

[ralfHielscher]

It seems that you are running MTEX on a very old Linux system. libc 2.5 is depreciated since 2006. Current version is libc 2.23. Basically you have two options:

• compile MTEX binaries yourself
• update your system or use a different system

Ralf.

[KKrishna1]

Hi Ralf,

How to compile MTEX binaries?

Many thanks, k

Besides, I got denied when I'm trying to get the log file. Also, when I was trying to use sudo!! to give myself the permission, it asks for the password and with a key icon behind preventing me from entering the password.

[kilir]

Hi Richard, not sure if it helps with your problem, but are you sure you are using mtex 4.4, your log says 4.023. Not sure what you mean with a key icon, but if you use sudo in a terminal, it will most often not give you any hint on what you are typing and if you are not in the sudoers file, you should also be getting a notification about that. Cheers, Rüdiger

[qzmdtc]

@kilir Thank you for your reply. The things is I was trying both version and it all doesn't work and now I kinda mixed them up. Though I'm thinking maybe the problem is due to the unsuccessful compiling METX binaries, I don't have enough basic coding knowledge to support me finishing the compiling myself. Btw, is there any command that can be used to check if the binaries is successfully compiled? Thanks

/Users/RichardQ/Documents/MATLAB/mtex-4.4.alpha.2/c/bin/maci64/pf2odf ; exit; Zhimins-MacBook-Pro-2:~ RichardQ$ /Users/RichardQ/Documents/MATLAB/mtex-4.4.alpha.2/c/bin/maci64/pf2odf ; exit; dyld: Library not loaded: /opt/local/lib/libfftw3.3.dylib Referenced from: /Users/RichardQ/Documents/MATLAB/mtex-4.4.alpha.2/c/bin/maci64/libnfft3.1.dylib Reason: image not found Trace/BPT trap: 5 logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.

So I create a path /opt/local/lib and copied libfftw3.3.dylib into it, but it still won't work.

Did you: Disable SIP? And install from the mtex page downloads where the binaries are already compiled?

[qzmdtc]

@zmichels I didn't disable SIP, wouldn't that cause some safety issue? The toolkit is directly downloaded from the downloads page. Thanks

[zmichels]

It will inhibit the install, so you should disable for that. My understanding is you can re-enable it afterwards (not sure if that's correct tho?), in case you are worried about some security issue. However, you'd likely need to disable every time you install a new version.

Hey,

It didn't work for me, even after disabling SIP. Any other suggestions? Thanks

[qzmdtc]

@zmichels @KKrishna1 Thx! Solved!

@KKrishna1 Did you actually install the toolkit? The install_mtex.m file in the folder. Though it is my guessing, I originally only used startup_mtex.m because the download page said so.

[zmichels]

Hey there, I have helped install it on some lab computers and laptops of colleagues in our lab. When I (or my colleagues) get this error, I take a step back and do three things:

1. Disable SIP
2. Make sure the download they retrieved was from this page link (rather than from the repo directly): http://mtex-toolbox.github.io/download.html
3. Make sure they're running the appropriate version of matlab.

100% of the time, these things have fixed our problems on a variety of macs. I do not mean to suggest that there aren't other troubles to be had... But that is all I know for any advice.

Best of luck and please keep us posted. Z

@qzmdtc Just wondering where is the toolkit, I did not install it. Thanks

[qzmdtc]

@KKrishna1 Download it under the download page http://mtex-toolbox.github.io/download.html Unzip it and then move it to the Matlab folder. Run the matlab and then type install_mtex in the command window. Then type check_tex in the command window, you should be all set if no error message pops up.

@qzmdtc @zmichels and ALL.Thanks, Guys. Working perfectly. Cheers!
