Dear ChimeraX Team, I'm currently working with the Boltz structure prediction tool in ChimeraX GUI (ChimeraX 1.10 Release Candidate (15 June 2025) ) and would appreciate your guidance on the correct command syntax—particularly when specifying the single or multiple protein components via the ChimeraX GUI command line. I would like to run Boltz predictions with the following specific parameters: * nstruct: 5 (Default is 1) * recycles: 10 (Default is 3) * seed: 42 (Random numbers of seed (integer), Fixed seed value ensures reproducible results) * steering: true (enables or disables the steering potential) I tried running the following command in the command line, "boltz predict protein sequences "MKALTQRPLD... (your protein sequence)" nstruct 5 recycles 10 steering true" but it doesn't work. Could you please provide an example of the correct command format for: 1. A single molecular component (e.g., one protein sequence). 2. A multi-component system (e.g., protein + peptide or multiple protein chains). Additionally, if there are any special considerations or formatting requirements for specifying multiple sequences or components in the GUI , I’d be grateful for your advice. Thank you for your time and support.
