Panedr reads a Gromacs EDR file and returns its content as a pandas
dataframe. The library exposes one function—the edr_to_df
function—that gets the path to an EDR file and returns a pandas
dataframe.
panedr
is compatible with python 2.7 and greater, and with
python 3.3 and greater.
import panedr
# Read the EDR file
path = 'ener.edr'
df = panedr.edr_to_df(path)
# The `verbose` optional parameter can be set to True to display the
# progress on stderr
df = panedr.edr_to_df(path, verbose=True)
# Get the average pressure after the first 10 ns
pressure_avg = df[u'Pressure'][df[u'Time'] > 1000].mean()
pip install panedr
The panedr
module comes with a series of tests. To run these tests,
install nose, and run:
nosetests -v panedr
