Gromacs system modification
This protocol performs modifications over a Gromacs System, specially over its trajectory.
- The modifications include:
Cleaning: removing waters and ions
Fitting: Fit trajectory to initial structure
Dropping: Cut a trajectory, saving only from first to last specified times
Subsampling: Subsample trajectory frames
Filtering: Perform low/high pass filters on trajectory frames
Input
Note
All parameters include a help button that gives further information for each of them.

The result of this protocol is a GromacsSystem
, containing the modified Gromacs files and trajectory. The user
can visualize the complex using Analyze Results.
Test
This protocol has an integrated test that can be run using the following command:
