FAQ: Why are some of the shapes missing?

Check the PDB file to ensure that the ring atoms are properly named. For most monosaccharides, they should be C1, C2, C3, C4, C5. If the residue is a sialic acid, the ring atoms should be C2, C3, C4, C5, C6, and O6. Example error message from command line: ERROR) vecsub: two vectors don’t have […]

FAQ: Why are all of the shapes missing?

First, try using a file that has already been tested, such as this file generated from the GLYCAM Web-Builder OR PDB ID: 3SGJ. If those files work properly, but your original does not, check the file to ensure the pdb is in the proper format (compared to the provided files). For example, a .pdbqt file […]
