Dear all,
A PAW pseudopotential is available for He in xml format from the JTH table:
http://www.abinit.org/downloads/PAW2/JT ... index.html
Is it possible to convert the xml format to .paw ? Or is the .paw format for He available somewhere else? I am about to test another DFT code, but this code only takes the Abinit .paw files for the pseudopentitals.

Re: PAW pseudopotential for He in .paw format
Hi,
The JTH table is still in beta test (that the reason why input files are not provided).
Soon, a public revised version will be available.
And a converter (xml2abinit) will be provided. But it's not ready (currently under writing).
Anyway, I don't know which code you are using but you should think to adopt the XML format which will be the future default format in ABINIT (because it's common to several codes); it is likely that new features will be only available in this new format (f.i. Hartree-Fock).

Re: PAW pseudopotential for He in .paw format
Dear Marc,
I am using XML formats of PSPs downloaded from
http://www.abinit.org/downloads/PAW2
The prob is that abinit-7.6.2 seems to have difficulty reading the PSPs.
The output halts immediately after this:
------------------------------------------------------
-instrng : 23 lines of input have been read from file GaAs_3C_paw60_ecut6.in
iofn2 : Please give name of formatted atomic psp file
iofn2 : for atom type 1 , psp file is PSPPATH/Ga.LDA_PW-JTH.xml
iofn2 : Please give name of formatted atomic psp file
iofn2 : for atom type 2 , psp file is PSPPATH/As.LDA_PW-JTH.xml
- inpspheads : Reading pseudopotential header in XML form from PSPPATH/Ga.LDA_PW-JTH.xml
forrtl: severe (174): SIGSEGV, segmentation fault occurred
----------------------------------------------------------------------------
I do not get any log files either. I have checked the PSP files to make sure they were not corrupted.
Also as soon as I replace the old *.paw PSPs, it just runs fine.
I would be grateful if you could give me some advice...

P.S. I was looking for a way to convert XMLs to .PAW format.

The input file for generating the PAW atmic data are available so you can download and install atompaw and change the input file to generate a "abinit paw" file.

Re: PAW pseudopotential for He in .paw format
Dear Jordan,
Thanks for your advice. I want to strictly use the xml psp (due to its finer quality).
So from what I understand from you, I have to take the xml parameters and generate its .paw counterpart-
So these paw formatted PSPs are the same xml PSPs only that they are in paw format?
Thanks for your attention.

Re: PAW pseudopotential for He in .paw format
Yes everything is the same since the input file for generating the data is the same, just the format is different.
Actually, the example I provided to you will generate both xml and paw format.
Or you can also upgrade you abinit version to the last one (check the abinit.org website) and this will probably fix the reading issue with xml.
