I built gnuradio and gr-ais, all ok.

However trying the command, it can not be found.

scott@scott-P5QC:~$ ais_rx -sosmocom -g35 -r250e3 > ais_pipe
ais_rx: command not found

scott@scott-P5QC:~$ ais_rx.py -h
ais_rx.py: command not found

File exists, so why is it being stupid?
scott@scott-P5QC:~/gnuradio/gr-ais/apps$ python ais_rx.py
python: can't open file 'ais_rx.py': [Errno 2] No such file or directory
scott@scott-P5QC:~/gnuradio/gr-ais/apps$ ls
ais_rx CMakeLists.txt
scott@scott-P5QC:~/gnuradio/gr-ais/apps$


from instructions here for gr-ais

This script has just modified /etc/group to place your userid '('$USER')' into group 'usrp'
In order for this change to take effect, you will need to log-out and log back

If you wish to allow others on your system to use the USRP1 device, you will need to use:

sudo usermod -a -G usrp userid

For each userid you wish to allow access to the usrp

As a python test, the os runs this clock python http://code.activestate.com/recipes/...ock-in-python/

I reboot and get this different error

"ImportError: No module named ais"

I was wondering if maybe the usb device needs to be plugged in first?
