Dear Chimera's users! First I wish Happy New Year to everyone! I am just switching from Chimera to ChimeraX that I am going to use in no-gui (batch) mode to prepare screen shots of protein-ligand interactions based on the protein-ligand docking poses. Basically I am loading a pdb file of the complex (consisted of protein and ligand in multi-model format) from the terminal of my macOSX. I have a template for a batch file created in the bash script on the fly, that I used 2 years ago with an early version of ChimeraX. # a batch file for chimeraX printf "open ${pdb} view; zoom 1.0; turn x 90; turn z -80; wait # options for appearance preset 'overall look' publication # set bg powder blue set silhouettes t; set silhouetteColor indigo; set silhouetteDepthJump 0.02 # make info of the screen 2dlab create title text \"${pdb_name}\" color red font gothic xpos .04 ypos .92 size 35 # options for light light depthcuestart .4 depthcueend .8; lighting full intensity 1.4 shadows true qualityOfShadows finer save image ${structure}/${pdb_name}.png format png width 800 height 600 supersample 4 transparentBackground false wait exit" > chimeraX.${pdb_name}.cxc" then I use it directly in terminal as chimerax-daily chimeraX.${pdb_name}.cxc" may you suggest some commands that I may introduce into my batch file to 1) delete all models from the multi-model pdb file with the exemption of the first model. 2) switch from cartoon to surface representation of the protein 3) visualize protein-ligand non-covalent interactions in the current model Yours with thanks Enrico
