Bug Hunting – Cuemol2: Molecular Visualization Framework, Changing Cell Dimension Symmetry cause the program does not respond and then Cuemol2.exe stops working !

Expected behavior

 

Changing Cell Dimension Symmetry

 

Actual behavior

 

The program does not respond and then Cuemol2.exe stops working

 

How to reproduce

 

    I was using Cuemol2. I downloaded file by using PDB feature. I did 200 Angström by using Symm Mol feature. Then i clicked Change Symmetry. I made change in Cell Dimension. I wrote 0.52 instead of 95.52. When i clicked to ok button, Cuemol2.exe does not respond and then Cuemol2.exe stops working !

 

    I am following this process while making this error:

 

• Get PDB usin accession code.. – Enter PDB ID: 1FN3 – Ok (Download PDB window) – Ok (Setup Renderer) – Symm Mol – 200 Angström – Change Symmetry – a=0.52 instead of 95.52 in Cell Dimension – Ok – Cuemol2 does not respond - Cuemol2.exe stops working

 

   This bug causes the program to stop working and shutdown itself, it should be fixed.

 

• Operating system 1: Windows 7 professional SP1 (32 bit) İntel Core 2 Duo 2.13 Ghz , 4 gb RAM

• Program Version 1: Version 2.2.3.430 (32 bit)

 

Recording Of The Bug

Changing the cell constant to 0.1 will results in too many symmetry operators generated within 200 angstroms. Such situation is abnormal, but possibly occurs by error of user input. To avoid this situation, I limited the number of symops generated in the symm renderer by "maxops" property of the symm renderer. The default value is 1000, which might be large enough for normal applications.
