I believe that issue was fixed on 10/19, so the fix is only in the 1.2 daily build unfortunately. I'll try to get an updated AddH bundle onto the toolshed today. Will alert you once it's available.

(Sorry for the duplicate - replied directly to you rather than to the bug tracker). That looks like a bug in AddH that's fixed in the daily builds (for which I unfortunately don't have an ISOLDE version yet). To avoid it, I'm afraid you'll need to delete the existing hydrogens before running AddH again ("del H; addh"). ________________________________ From: ChimeraX <ChimeraX-bugs-admin@cgl.ucsf.edu> Sent: 04 December 2020 17:41 To: kartik.manne@duke.edu <kartik.manne@duke.edu>; Tristan Croll <tic20@cam.ac.uk> Subject: Re: [ChimeraX] #4018: ISOLDE: OpenMM: find_glycan_template_name_and_link: multiple bonds between residues #4018: ISOLDE: OpenMM: find_glycan_template_name_and_link: multiple bonds between residues -------------------------------------+--------------------------- Reporter: kartik.manne@… | Owner: Tristan Croll Type: defect | Status: assigned Priority: normal | Milestone: Component: Third Party | Version: Resolution: | Keywords: Blocked By: | Blocking: Notify when closed: | Platform: all Project: ChimeraX | -------------------------------------+--------------------------- Comment (by kartik.manne@…): {{{ Hi, I'm also getting this error and the program crashes.

Okay, I have uploaded an AddH bundle to the Toolshed that contains the fix. You should be able to install it via the Tools→More Tools... menu item.

Note:
See TracTickets
for help on using tickets.
The problem here is that you have something wrong with the bonding between sugar residues a515 and a516 - there are (at least) two bonds between them, which is almost certainly not what you want. I'll tweak the code so cases like this bring up a more informative dialogue and focus the view on the offending site, but for now you'll want to take a close look to see what's wrong. Note that the ISOLDE menu has a few simple tools included that can help with the editing necessary to fix this (add/remove bond, add hydrogen).
