[MSNoise] problem in compute_dtt (master version with ACC)

[Christos Evangelidis]

Hi all,

I have the following error trying to calculate the DTT with the command
(master version)

msnoise compute_dtt -i 999

for 2 stations with autocorrelations. It seems that the script stacks in a
some days (eg. 2011-02-27).

Any idea?

Cheers,

Christos
