How to select all the alanine residues of chain-A and glycine residues of chain-B? How to count the total number of selected residues? How to display residue information on hovering the mouse over it like in UCSF chimera? Thanks in advance -- Prathvi Singh, Research Fellow, Department of Biological Sciences & Bioengineering, Indian Institute of Technology, Kanpur-208016
