"Segmentation fault (core dumped)" with fitsvsl

Dear ATATers,

I used the mcsqs in ATAT to generate a 12-atom structure (hcp based),

and then used the fitsvsl to calculated the stiffness and bond length scheme, however,

it tells me "Segmentation fault (core dumped)". To my
surprise, the same command
"fitsvsl -er=11.5" on the ordered Pure A, Pure B and other ordered structures shows no

this sign. Can you tell me the way to solve it ?

In addition, the tool fitfc also apears this sign when used on the SQS structure.

The following is the files I used,

Dear Alex and ATAT users,

I have tested my structure again, but copy the str.out to str_relax.out, i.e., there

are two same SQS withou relax in the present documentary. Then, run the command " fitsvsl -er=11.5"

it succeed. However, the question comes, i.e., the fitsvsl could not recogonize my str_relax.out

what should I do next?

Looking forward to your reply. Thank you.

Sorry about this problem. To debug this I would need a .tar file containing all the input files needed for your fitsvsl command.
