Can’t load external url with sdf file

[Abylay Ospan]

Hello,

thanks for this great tool! Unfortunately, I can’t load the following external URL:
https://static.molinstincts.com/sdf_3d/dopamine-3D-structure-CT1000589152.sdf

It shows me following error in browser developer tool console:
Access to XMLHttpRequest at ‘https://static.molinstincts.com/sdf_3d/dopamine-3D-structure-CT1000589152.sdf’ from origin ‘https://durrantlab.pitt.edu’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Looks like you need to specify "Access-Control-Allow-Origin: *" header in the response but I’m not sure.

Thank you!

Hi Abylay. Much thanks for your interest in ProteinVR. I was able to reproduce the error on my computer. Unfortunately, the problem isn’t that ProteinVR can’t load the remote file. It’s that the server where the remote file is hosted won’t allow ProteinVR to access it. To fix the problem would require changes on the remote server itself. You may wish to contact the maintainer of molinstincts.com to see if they would be willing to change their server settings.

For what it’s worth, I’ve found that uploading SDF files to https://gist.github.com/ is a good way to make them publicly available. Here’s an example of loading a model from gist, in case it’s helpful: https://durrantlab.pitt.edu/pvr/?s=https://gist.githubusercontent.com/durrantlab/55ff21a12a851d3602efcddd7ad4f699/raw/baa70e29c7377fb07ba3e37e2783daffaa01eae3/1xdn.pdb&st0=All–Ligand–Stick–Element&st1=All–Protein–Cartoon–Spectrum&cx=0&cy=2.6281&cz=-8.0649&crx=0&cry=0.00001&crz=0&crw=-1&e=environs/blood/&sh=false&hs=true

I’m currently working on an update to ProteinVR that will allow users to upload files from their local computers too, eliminating the need for remote hosting all together.

Take care.
