The link to access the technical white paper on the experimental design, data acquisition, and informatics methods from the page [Visual Coding – Neuropixels — Allen SDK dev documentation](https://allensdk.readthedocs.io/en/latest/visual_coding_neuropixels.html) looks broken. I am currently writing a manuscript where I have to cite the white paper. It would be great if the link could be revived. Also, is there a DOI that I can refer to for the white paper? I get the following when I click the link to the whitepaper: ![image](https://canada1.discourse-cdn.com/flex027/uploads/brainobservatory/original/2X/2/2bd6c39de17eb2371ddb7c6eed92d372f22137a9.png) ---

Hi, Thank you for letting us know about the technical access issue. Could you try again as I think that the matter has been resolved? Thank you ---

Hi Susan, Thanks for your reply. Unfortunately, I still see the same “The site cannot be reached” message while clicking the link: [https://brainmapportal-live-4cc80a57cd6e400d854-f7fdcae.divio-media.net/filer\_public/80/75/8075a100-ca64-429a-b39a-569121b612b2/neuropixels\_visual\_coding\_-\_white\_paper\_v10.pdf](https://brainmapportal-live-4cc80a57cd6e400d854-f7fdcae.divio-media.net/filer_public/80/75/8075a100-ca64-429a-b39a-569121b612b2/neuropixels_visual_coding_-_white_paper_v10.pdf). I have tried in other systems, it still shows the same error message. Cheers, Indra ---

@SvenOtto Thank you very much. This is really helpful. As I am preparing my manuscript, where I am citing the technical white paper, is it okay if I just put the old link as a reference? Or do you have a DOI for the white paper? I am worried about referring to a dead link in my paper. I want to cite it properly so that others who read my work can find your white paper. Thanks for helping me out with this. Cheers, Indra
