Electroformation script for controlling an Agilent 33120A to create giant unilamellar vesicles (GUV). See this protocol for details.

The script generates a

1. 30 minute sine at 10 Hz ramping linearly from 0.05 to 1.41 Vpp
2. 120 minute sine at 10 Hz at 1.41 Vpp
3. 30 minute square at 4.5 Hz at 2.12 Vpp.

cd guv-electro
./guv-electro

Example usage

./guv-electro

Test script (argument multiplies the total run time):

./guv-electro 0.01

Run with no hangups, log the output, and tail the log file

./run-guv

Watch the output

tail -f nohup.out

To quit the job midway through, find the PID of the python process and kill it

ps
kill PID
