Hi Ma Xiao, Mind the spacing. You can take a pseudo file from the examples directory and replace the numbers and labels you want. That way you ensure having a *format* the ATOM program will understand: ATOM does not have the FDF features that SIESTA has, so you have to not add a single more nor a single less space in the inp file.
Now, if you are certain you are complying with the proper format of the inp file, get into the directory pg.sh has generated for you, and look inside the OUT file in there. That file will provide you with more info on where the problem is coming from. Best regards. -Salvador. ----- Original Message ----- From: max...@umich.edu To: siesta-l@uam.es Sent: Wednesday, February 24, 2010 5:24:25 PM GMT -05:00 US/Canada Eastern Subject: [SIESTA-L] Error for pseudopotential generation Hi, all: When I run the program to get the pseudopotential of Au atom, I found the error below. cp: cannot stat `VPSOUT': No such file or directory cp: cannot stat `VPSFMT': No such file or directory ==> Output data in directory Au.tm2 ==> Pseudopotential in Au.tm2.vps and Au.tm2.psf (and maybe in Au.tm2.xml) I cannot find the files of Au.tm2.vps and Au.tm2.psf.
