Description
Hi there,

I am trying to run antechamber on my ligand and add a AM1-BCC charge. However I keep getting an error. I have searche the internet and also tried to follow the suggestions but they do not work. Please could you assist?

Using Amber 20 recommended default charges and atom types for standard residues
Assigning partial charges to residue 0 (net charge -3) with am1-bcc method

The charge computation itself worked.

It looks like the OpenGL shader error happens as soon as you start ChimeraX before opening any data. Is that right?

That OpenGL shader is not from ChimeraX code we wrote. I don't know whether it is a Qt window toolkit shader or an Amber shader (does Amber use the GPU, and would it be initializing at startup?).

I guess I'd think it is a Qt window toolkit shader that is being reported as having a problem. That might make some part of the ChimeraX user interface not render correctly.

It very likely is a problem with your computer's Intel graphics driver. Updating your graphics driver is probably the only way to fix that.

Good day,

I hope you are doing well.

Thanks for your response. However, my graphic driver is up to date. I have even downloaded this software onto another laptop and the error message is still present at start up. Surely this cannot be for all devices and is an issue with the software?

Kind regards,
Xylia

Your Intel graphics driver listed in this bug report is 20.19.15.4549 from 2016. It is almost surely the source of your problem. If that is the latest graphics driver available for your machine then there is nothing I can suggest. That graphics error that appears at startup might cause blank ChimeraX user interface panels, but it would not effect Antechamber in any way.

If you get the same graphics error on a different computer then that is bad luck. Of the thousands of Windows ChimeraX users no one else has reported that graphics problem.

I am guessing that you really were not trying to report the graphics error at startup, but were instead trying to report that Antechamber failed. It is not apparent from the Antechamber output you sent whether it computed charges or not.

I am reassigning this bug report to the person who knows about the many reasons Antechamber fails.

[Eric Pettersen]

As mentioned in the first comment, the charge computation worked. It took two tries -- the first attempt with a faster set of parameters failed, but the second attempt with a slower set of parameters worked.

[Tom Goddard]

Ok, so we need the reporter to explain what error they are reporting. If it is the graphics driver error, there is nothing we can do about a broken graphics driver if they cannot update it, and we can close this ticket.
