To run a Bruco:

ssh into the cluster via:

> ssh albert.einstein@ssh.ligo.org

I usually run on either the Caltech cluster or LHO cluster. Sometimes the data is in one place or the other due to issues. I will provide instructions for both.

For Caltech cluster- choose a computer that doesn't have a specific purpose (like j. general purpose)

example bruco command:

> python -m bruco --ifo=H1 --channel=CAL-DELTAL_EXTERNAL_DQ --gpsb=1376321262 --length=400 --outfs=4096 --fres=0.1 --dir=/home/elenna.capote/public_html/brucos/CAL_1376321262 --top=100 --webtop=20 --plot=html --nproc=20 --xlim=7:2000 --excluded=/home/elenna.capote/bruco-excluded/lho_excluded_O3_and_oaf.txt

This is running a bruco on CAL-DELTAL_EXTERNAL_DQ for a given gps time and length with frequency resolution 0.1 Hz. I chose a save directory in my public_html folder so others can access it and I named it after the time and channel "CAL_1376321262". Remember you can run Bruco on GDS Strain channels (recommended). If you run for a time when the calibration lines are on in a channel that has them (like cal delta L or gds calib strain), you will need to add the calibration line channels to the excluded list (I am not sure they are on there).

The excluded channel list is shown. To view which channels are in that list you can run

> vim /home/elenna.capote/bruco-excluded/lho_excluded_O3_and_oaf.txt

To edit the channels in vim, press the "i" key, add the channels, press "esc" and save by typing ":wq".

You can copy over the excluded channel list into your own directory if you want.

To view the results, go to https://ldas-jobs.ligo.caltech.edu/~albert.einstein/[directory you saved them in]

For LHO cluster, similarly choose a computer that looks available.

similar command as above, except my excluded file is here:

> /home/elenna.capote/bruco-excluded/lho_DARM_excluded.txt

To view the output of the LHO bruco, go here: https://ldas-jobs.ligo-wa.caltech.edu/~albert.einstein/[directory you saved them in]

Back to the example bruco command- using -h will help explain a lot of the options, but it's something like "top=n" returns the top n channels with coherence, "webtop=n" shows top n channels on the web page, etc. There are plenty of other options available and great documentation.
