Release notes

Version 1.9.0

  • New LoopClosure step is included in the PELE algorithm to explore intrinsically disordered loop conformations which are not accessible with ANM. It applies for RNA too.

  • Rotamer libraries are modified. When applying clash relieve in the side chains, cyclic links (proline and nucleotides) where broken. Now, there are extra rotamer libraries suitable with side chain relocation (only sampling dihedrals that are not part of a cycle), and the general ones for side chain prediction. Now rotamer libraries are able in RNA, so the exploration is enhanced.

  • Fixed bug regarding the selection for LocalNonBondingEnergy metric.

  • Add OBC parameters for Zn2+.

Version 1.8.1

  • New removeBulkMovement flag in PeleParameters to activate/deactivate the removal of the bulk movement of the system.

  • Optimized the interface region definition whenever perturbAllAtOnce is true. Now the interface region should not include side chains located at the interface of atomsets that are being moved together with perturbAllAtOnce.

  • Improvements for the side chain perturbation refinement algorithm.

  • New parameters to control side chain perturbation:

    • sideChainPerturbationFrequency

    • numberOfStericTrials

    • overlapFactor

    • numberOfTrials

  • Support for trajectories in the EnergyCalculator command. Two new parameters are added accordingly:

    • trajectoryPath

    • energyReportPath

Version 1.8.0

  • New Non Bonding Energy By Selection metric.

Version 1.6.1

  • New algorithm is performed when doing a Ligand Perturbation, if the Ligand has a large number of rotable bonds. The rotable bonds now will be randomly selected following a freedom criteria. This is done in each group.

    • If there are 3 or less rotable bonds, all are studied and no random selection is done.

    • If there are more than 3 rotable bonds:

      • If the lowest resolution is < 30, 3 rotable bonds will be randomly selected.

      • It not, 5 rotable bonds will be randomly selected.

  • Multiple spherical boxes can also be defined for the ligand perturbation with the new MultiSphericalBox option.

  • New WaterPerturbation (wMC) step is included in the PELE algorithm to explore water sites along the simulation with a Metropolis Monte Carlo approach.

  • WaterSites are regions where the user can specify explicit water molecules that need to be perturbed inside a certain spherical box in the wMC step.

  • LigandPerturbation algorithms are changed to allow the ligand to be placed over explicit water molecules that are perturbed in the wMC step.

  • New verbose mode allow the user to chose between an extended or a condensed logfile.

  • Some repeated and useless lines were removed from logfile ouputs.

  • Symbolic links to Data and Documents folders are automatically created when PELE initiates.

  • In case the output folder does not exist, it will be created when PELE initiates.

  • Several issues with PELE tests were solved in this release.

  • Now when a atom is not found, instead printing “total mass is too small: 0” tells which atom and where is located.

  • When running PELE in serial mode, Complex keyword failure has a better error description.

  • Many other minor changes are introduced to improve the performance of PELE and to fix small issues.
