Hi Eun-Suk,

I’ve seen this issue before, sometimes the Run Feff button doesn’t activate even though everything else seems correctly loaded. One workaround that usually works for me is to click through the tabs in order, especially:

1-D XRD Pattern
Feff Input Text
Feff Output Text, etc...

Just navigating through these tabs seems to trigger the GUI to recognize that the CIF is there and settings are properly loaded, and then the "Run Feff" button becomes clickable.

Hope this helps.

Best,
Esmael

Hello~ all

I opened the cif file in CIF Browser. I couldn't make feff.inp in this Browser. In a previous version, feff.inp was generated. However, it isn't now. What is the problem?

I installed xraylarch in anaconda virtual system as following:

(base) C:\>conda update --all
(base) C:\>conda create --name xraylarch
(base) C:\>conda activate xraylarch
(xraylarch) C:\>conda install -c conda-forge python=3.9.10
(xraylarch) C:\>pip install torch
(xraylarch) C:\>conda install -y -c conda-forge wxPython pymatgen scipy h5py matplotlib
(xraylarch) C:\>conda install -y -c conda-forge openbabel tomopy
(xraylarch) C:\>pip install epicsapps
(xraylarch) C:\>pip install xraylarch
(xraylarch) C:\>larch -m

I have been using Window 10 system

Best regards,
