Dear Thomas et al.,
I installed MSNoise 1.5 again and started the workflow again.
When I run "msnoise scan_archive --init" with MSNoise 1.5 and Python 1.7, the result by screen is:

If the seismic files in MSeed format are OK, if in other times the MSNoise did run correctely, I don't understand why "msnoise scan_archive" not find the MSeed files ?
Thanks for your suggestions,

At the beginning everything works fine, but because it takes a long time to
make the computation (around 5 days), every time that I come back to see
the results this happens. I am working with MSNoise 1.4 and I don't know
how to upgrade to MSNoise 1.5.
Does anyone know how to fix this?
Thanks in advance!
Oscar
I have set "maxlag" to be 300 s, so I would like cross-correlations centred on zero, +/- 300 s. Instead, MSNoise is giving me cross-correlations from 0 s to 600 s. In the SAC header B = 0.000000e+00, and E = 6.000000e+02. Why is this happening? How can it be corrected?
Thanks in advance,
Emily

Hello everyone,
I was wonder if it is possible to plot the correlation coefficients using MSnoise. I know that I have to compute the CCF reference first and then using the moving-window stacks with a daily CCF I can get the correlation coefficients, but how do i get them plotted?
I will appreciate some help!
Thank you.

I was doing initial scan of my archive: msnoise -t 2 scan_archive --init
This is a SDS structured archive and msnoise stumbled upon a shell script, tmp.sh, in the wrong place after successfully scaning 273271 files:
[msnoise@gaur SUH]$ pwd
/mnt/archive/2016/IM/SUH
[msnoise@gaur SUH]$ ls
HHE.D HHN.D HHZ.D tmp.sh
[msnoise@gaur SUH]$
The scan crashed and complained that tmp.sh was not a direcory. Shouldn't msnoise just ignore files of wrong format?
I am running msnoise 1.5 on CentOS Linux release 7.2.1511 machine ... if that is of any interest :)
cheers
