Feature #846

Warning messages should be added to programs reducing the precision of coordinates/velocities etc.

Added by David van der Spoel about 9 years ago. Updated over 4 years ago.

Target version:


When pdb2gmx processes a pdb file to a gro file precision is lost. The same can happen in editconf or trjconv. A warning message should be issued when this occurs.

In principle this would be neat to have for the user, but it might run contrary to the idea of increasing modularization if the highest-level user program needs to be aware of the implementation detail of every single possible output format (what future sub-option to TNG will preserve vs. reduce precision, for instance?).

In particular, many of these minor features start out as nice-to-have, but a couple of years later they lead to lots of extra code we need to maintain. I think a better solution would be to have a text-based description of each output format available in an output module, and then leave it up to the user to decide. If they pick a file format that does lossy compression, that is simply what they will get.

  • Status changed from New to Closed
  • Target version changed from 5.x to future

Three year old feature, but with no activity whatsoever, so I'll assume even David doesn't think it isn't very important. Closing for now - feel free to reopen when somebody plans to actually work on it.
