Multiple Whole Profile fitting Main Page

MWP-fit is a program for evaluating diffraction profiles using the method of Multiple Whole Profile fitting. If you want to know more about the method and the program, click here. A detailed help is available in the documentation page.

Please check and accept the COPYRIGHT terms before proceeding. By accepting the terms and conditions and filling up the (C)MWP Registration form, you'll get access to the (C)MWP program package, you can either download it and install it on your own linux computer, or by using your username and password you can use (without the necessity of any software installation) the WWW frontend of the program (this page).

IMPORTANT NOTE to previous users: due to restructurization of the CMWP frontend, all older accounts were deactivated and the old data files were archived and deleted. We are sorry for the inconvenience. If you need your old data, please contact us. Please register using the new (C)MWP Registration form (you can use your old username and password) and either continue using the WWW frontend or download the program and use it on your own computer.

Users can acces the program via this page:
you can upload your profile files,
view the list of your samples,
or start the evaluation program.
You can also view the results of previous runs.
There is also a documentation page.
Please note that in order to save disk space, all data (which is stored in the CMWP frontend) older than six months will be automatically deleted.

Alternatively, you can go to the CMWP download page.

Here you can find some example data which might be useful for testing:

Cu-ECAP-dat: peak profiles of an ECA pressed copper sample, measured on a Nonius FR 591 special double crystal high resolution diffractometer with negligible instrumental effect (Ribarik et al., 2001). This data should be evaluated by the MWP method.

The physical parameters are given in the corresponding .ini files.

A similar procedure has been recently developed, called the method of Convolutional Multiple Whole Profile fitting, which is more sophisticated compared to the MWP method, so you should use the CMWP method when possible.

MKDAT is a program for preparing X-ray diffraction data for the MWP program. The functions of the program: (i) stripping off background, (ii) separation of overlapping peaks and (iii) deconvolution of instrumental profiles. Follow this link to download it.
