Hi During the auto dock vina operation, when building the grid box. What is the unit of the dimensions. I will equally like to know how to find the grid spacing value. Best regards.
Chimera questions should be sent to chimera-users@cgl.ucsf.edu (CC’d here). The Autodock Vina tool in Chimera does not have a grid spacing setting. It only has the box center and size, which are in X,Y,Z coordinates of your atomic structure. Atomic structures are generally in Angstrom units. <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/vina/vina.html> Maybe there is a setting to control grid spacing if you downloaded and used the Autodock Vina program directly (not using the tool in Chimera) but I do not know. You would have to look at the Autodock Vina website for that information. <http://vina.scripps.edu/> I hope this helps, Elaine ----- Elaine C.
