Wrong XA format

[Dalhte]

Hello there
I'm running the Finder package that used oLego. I'm having this error message :

Error: input 2 720: Wrong XA format.
The oLego indices output files are :

output (truncated by me now):
[BWTIncConstructFromPacked] 10 iterations done. 100000000 characters processed.
[BWTIncConstructFromPacked] 20 iterations done. 200000000 characters processed.

[bwt_gen] Finished constructing BWT in 268 iterations.

And the error file :

Can you help ?
