Hello Vasp admins and users,
I wanted to know if there is a way to write WAVECAR file in ASCII text format, or to convert the binary WAVECAR file into ASCII text format. I am doing this because I want to access individual wavefunctions.
Thanks!

go into the code where it is actually written to file. put in some line to produce a formatted output with whatever precision you might want.
CAVEAT: this file can easily become HUGE. The choice of binary had a reason ...

please note that WAVECAR only contains the PW coefficents of the wavefunction. Unless you are absolutely sure that the corresponding basis functions are generated appropriately, the information written on WAVECAR is useless
