RELEASE NOTES AND BUG FIXES

 

** VERSION 2.1.0 **

(28 July 2017)

Release Notes

  • An interface between DLPGEN and ForConX has been included in the code. This new feature allows the creation of input files for LAMMPS, CHARMM and AMBER.

  • New internal checks have been included in the code. For example, the program is now able to check the total charge of the system and gives warnings if the results are different from zero.

Bug Fixes

  • Minor bugs fixed.

 

 

** VERSION 2.0.2 **

(15 December 2016)

Release Notes

  • IF functions can now be used in the GEN files to customize options for GROMACS or DLPOLY input files. Similarly, IF functions can now be set to read/ignore polarizable parametrizations and symmetry operations.

Bug Fixes

  • Corrected bug that led to a program error when the "-14excl" argument was used.
  • Corrected bug when a REVCON file was used.

 

 

** VERSION 2.0.1 **

(12 October 2016)

Release Notes

  • In GROMACS input files, the improper dihedrals are now set as function 4 instead of 5 (see Gromacs manual for more details). This modification only modifies the data printed in the *log files, where a new entry for improper dihedral energy is added.

  • A new Force field consistency check was implemented.

Bug Fixes

  • Fixed issue related with 1-4 interactions in the GROMACS input files.

 

 

** VERSION 2.0.0 **

(31 August 2016)

Release Notes

  • GROMACS input files can now be directly generated using DLPGEN. The program generates the files "molecular.itp" (that include all force field informations), "topology.top" and (as before), a "CONFIG.pdb" containing the system initial conformation (PACKMOL can still be called).  These files can then be directly used to run "grompp". In principal, most of the options available for DLPOLY can be used to generate the GROMACS files (including the use of modified LJ parametrizations - see Version 1.0.1:Rev.007).

  • Support for "COS4" dihedral functions.

  • Revision and update of the available input files for DLPGEN.

Bug Fixes

  • Some error reports were improved.
  • Fixed issues related with reading of input files.
  • Minor issues have been fixed.

 

 

** VERSION 1.0.1 **

(5 February 2016)

Release Notes

  • The mixing rules for the Lennard-Jones (LJ) parameters can now be specified by the user. This can be performed in two ways: (a) The LJ parameters for a specific pair can be directly indicated; (b) by changing the mixing rules. If we consider atoms a and b, we have that (e.g.): σab = (σa * σb) / n and εab = (εa * εb) ^ (1 / n). By default n = 2, but this value can be changed for all mixing rules involving a specific atom.
  • A verbose mode was included to help addressing errors while running the program.
  • Update of the program manual.

Bug Fixes

  • A bug in the force field file error report was corrected.
  • A problem in the analysis of bonds containing bromine atoms was corrected.
