Thank you for the tutorial! May i know if you were to set the unknown peaks into the background peak, does the final refinement results still reflects your crystal properties accurately? Thanks
🤪🤪🤪 this is trick! Hereby refinement not goes to differ calculated and observed peak, but author have managed to eliminate! And chi2 goes drastically easy! 😛
I think the crystal properties are still reflected, but wt% of phases obviously would be wrong. To perform Rietveld method to get a "good" refinement, do not just see the chi2 value, let zoom and evaluate the fit of peak positions, peak width, relative intensities, absolute intensities.
Hola, muchas gracias por el video, cuan ajusta el background, también lo haces a los picos, pero veo que son bastante pronunciados como para pertenecer al fondo o background, entonces tengo las dudas siguientes . Eso no afecta el refinamiento?, esos picos no pertenecen a otras fases? y por que a esos picos los ajustaste como Background? quedo atento a tus respuestas
Hi, does performing the Rietveld refinement in GSAS-II also automatically perform the Rietveld phase quantification? (because I see the weight fraction showed when you finish Rietveld refinement in 21:59)
If I have a xrd of LaB6 then how to get the instrument parameter file from it. Or for any refinement if we don't have the instrument parameter file for a particular wavelength then how can we perform refinement in GSAS 2?
Hello. Thanks for have done a multiple phase refinement in GSAS-II, it's pretty difficult to find one. I just wanted to know about the Instrument Parameters, you got a value around 367 for parameter U. Is it accurate? I checked Taylor's video, and he got some pretty high value too.
Sir, How to make an output file for the electron density mapping from GSAS II refinement? For example in GSAS I, it can create the .grd and .fob files for the mapping.

What should be the range of u,v,w?
You are awesome Bro.
You are helping me so much. Thank You!!!
Hello! Do you offer refinement course using the GSAS-II? I work with doped samples, and even looking to the tutorial, I still have questions. Thanks
Use Fullprof software

Yes
This video is so helpful, I appreciate it. Thanks a lot@@NanoencryptionSKP
Really useful, thank you
Thank for this tutorial. Where I find the data to CoO and Co3O4 to download? I would like to do this refinement too.
Can you please do a tutorial for TiO2 (Titanium dioxide) I really need to see the process to understand how to use the program , thank you in advance
I do not have XRD Pattern of TiO2 material. If you have then please send me.
If I have a xrd of LaB6 then how to get the instrument parameter file from it.
Or for any refinement if we don't have the instrument parameter file for a particular wavelength then how can we perform refinement in GSAS 2?
Then go through FullProf software..
how can i move this line zero?

Nice tutorial! Could GSAS II export Rp and Rwp value? Thanks in advance!
is the data export from the cif file considered calculated data?
Thank you. so great
Sir, How can i contact you?

Does anyone know why I am unable to access the original audio?
Is there a way to calculate the electron density in the unit cell using GSAS?

hello , help me wiht my refinement
What's your material?
