If I run with 1 PELE iteration with spawning: independent I got one cluster:

Then when going to the line tries to to pick up the metric 5 because in the report I have "metricColumnInReport" : 6 and dies because I do not calculate this metric.

    if len(self.metrics) and self.metricCol is not None:

      return self.metrics[self.metricCol]

IndexError: 'index 5 is out of bounds for axis 0 with size 4'**

Idk if its my mistake to include "metricColumnInReport" : 6 but looks strange that I just did a 1 PELE (spawningtype:independent) iteration that I though it needs no clustering and at the same time the script is outputting 1 cluster and trying to pick up the metric 5 because in the report I have "metricColumnInReport" : 6.

I get an OSError when I run MSM analysis for second time over the same folder. We may want to handle this exceptions for the program not to crash. If you disagree, close the issue.

If Adaptive & pele control files have different report name the next error arises:

We could avoid that by templetazing pele control file

We have been checking the documentation on condition and cluster values (heavyside) and it is not clear to me what refers to contacts and what to rmsd values. Maybe we could set a explanation of a practical example?? Feel free to close the issue if you do not think is relevant (:

Part of docs:

heaviside (default), where thesholds (values) are assigned according to a set of step functions that vary according to a ratio of protein-ligand contacts and ligand size , r, (conditions, see below). The values and conditions of change are defined with two lists. The condition list is iterated until r > condition[i], and the used threshold is values[i]. If r <= conditions[i] for all i, it returns the last element in values. Thresholds typically vary from 5Å in the bulk to 2Å in protein pockets. This method is preferred, as it optimizes the number of clusters, giving more importance to regions with more contacts and interactions, where metastability occurs. Default values: [2,3,4,5], default conditions: [1, 0.75, 0.5].

When trying to pip install AdaptivePELE the future module is not automatically installed, making the software fail:

ImportError: No module named builtins

Shouldn't we set that automatically on the setup.py?

File "AdaptivePELE/atomset/atomset.pyx", line 663, in AdaptivePELE.atomset.atomset.PDB.initialise
File "AdaptivePELE/atomset/atomset.pyx", line 575, in AdaptivePELE.atomset.atomset.PDB._initialisePDB
ValueError: The input pdb file/string was empty, no atoms loaded!

Could it be possible to discern between not finding the input file and having the resname wrongly spelled?

Error:

"/work/NBD_Utilities/PELE/PELE_Softwares/adaptive_types/v1.6.2_python3.6foss2018/AdaptivePELE/simulation/simulationrunner.py", line 781, in selectEquilibratedStructure
if energyColumn > similarityColumn or similarityColumn is None:
TypeError: '>' not supported between instances of 'int' and 'NoneType'

The clause if in simulation/simulationrunner.py", line 781 looks worng as if similarityColumnis none can't do the comparison (>).

Would that be possible?

Thanks!

Description

We detected that the predefined perturbation box used in the Adaptive's equilibration is wrongly located. It should be placed at the COM of ligand according to the first input PDB structure. However, even though we set a box radius of 6Å, the resulting center of the perturbation box was too far away for PELE to accept any move of the ligand.

Support

A zip file with the simulation data to reproduce this issue.

Description

We have been using the equilibration of Adaptive to obtain different initial structures of a small ligand. The idea is to launch afterwards an unbiased PELE simulation starting from different initial positions to cover as many regions as possible in a specific protein cavity. The problem we found is that the default (and only) option to run this equilibration is with a 2Å radius spherical box. As a result, the structures resulting from the equilibrationCluster clusterization are all located in a very small region and they are not spread around the cavity we are interested in exploring.

Solution

The most straightforward solution would be allowing the users to change the hard-coded 2Å-spherical box with the radius they want.

Hi,

I noticed in the constants /gpfs/projects/bsc72/PELE++/bin/rev12025/Pele_rev12025_mpi is required to run this. Is this a part of PELE? I didn't find any matching file in the PELE repo.

Thanks.

In adaptive, the templetized pele control file is read and and saved in a different file after substituting the required fields. The new pele control file is saved using the makeWorkingControlFile() function in line 215 of simulation/simulationrunner.py. By default, makeWorkingControlFile substitutes all ' characters in the string by ", see line 231 of simulation/simulationrunner.py. Perhaps there was a good reason to do this, but it's a problem when trying to use as ANM nodes atoms that contain the ' character in their name. This is the case for example in RNA molecules using the AMBER99sbBSC0 which is implemented in PELE (e.g. H5'', C5', C2').

Thus one cannot include the following configuration:

"algorithm": "CARTESIANS", "nodes": { "atoms": { "names": ["P_", "C2", "_C4'"]}}

Because it's transformed into:

"algorithm": "CARTESIANS", "nodes": { "atoms": { "names": ["P_", "C2", "_C4""]}}

Which is not a properly formed json control file (additional ")

Thanks :)

When running an MD simulation with constraints and restarting from a checkpoint file, the constraints dictionary is not updated with the renumbered residues, so if residues from the initial pdb need to be renumbered, it will later fail to find the atoms to constrain.
