I am working on fullprof software to refine my XRD data of ZnO.But I am getting run time error- forrtl severe (24) end-of-file during read unit 4. what could be the possible error ?
You should recognize with the algorithms in order to deduce the origin of the error.
On which operating system you are using the FullProf? If it is Linux or Mac then there might be few bugs and try to use FullProf in Windows machine. If it is already on windows, share the pcr file and the data, if you wish I could have a look.
Thank you so much
As of now I have resolved the bugs .If I get any further any further issues I will surely contact you Sir
As far as I know ZnO crystallysis as cubic or hexagonal phase. As hexagonal it only has a free parameter for oxygen (z), the cubic even has no. I hope you know that there are very likely more relevant factors than the z-coordinate for O which affects the intensity distribution in your XRD pattern? What I want point out: FullProf is certainly a fantastic tool but the best R values do not automatically describe the correct atomic coordinates. You should ask yourself whether other parameters like inaccurate calibration, sample preparation, texture, substitution or occupation are perhaps more influencing... Fullprof does not replace a critical review of possible errors which are NOT the result of FullProf but of inaccuracte and unsuitable assumptions for the refinement. Mathematically you can everything "improve"...
