Error in running abinit

[aes]

Hi,
I'm new abinit user. After installing abinit, I employed some tutorial input files for exam but I get the below in each run:
" ABINIT 8.10.1

Give name for formatted input file:
ab.in
Give name for formatted output file:
ab.out
Give root name for generic input files:
abi
Give root name for generic output files:
abo
Give root name for generic temporary files:
tmp

--- !ERROR
src_file: m_dtfil.F90
src_line: 1138
mpi_rank: 0
message: |
Checks for existence of file ab.in
but INQUIRE finds file does not exist.Action: check file name and re-run.
...


abi_abort: decision taken to exit ...

"

While the input file and files are in a same folder. Anyone knows where this problem arising from? Many thanks in advance for your help.

Dear aes,
Sounds like the ab.in input file is not found by the code, I cannot tell you more than that, you probably have a problem of declaration of the input file from the ".files" file and the real input file name in the folder.
Best wishes,
Eric
