[Pw_forum] Problem with q2r.x running

[Viet Bac]

Dear QE users,
I am doing EPC calculation for supercell and I got error with q2r.x when I
want to do q2r.x to bring force constants and el-phon coefficients (results
from ph.x)  to real space. My supercell includes ibraiv =0, and I search
somewhere in this forum, Dr. Stefano had stated this problem has solved
already.
So anybody can help me to explain this error? (Is there any problem with
a2Fq2r.* data??)
I attached the error

 /../espresso-3.2.3/bin/q2r.x <q2r.in> q2r.out
forrtl: severe (59): list-directed I/O syntax error, unit 51, file
/../a2Fq2r.51

And I use K-points grid 1*1*40 in scf calculation and q-points grid 1*1*10.
