Hi all, 

We store our alignment files on aws s3. I would like to be able to open them with IGV without needing to download them completely, but I can't find an optimal solution.

If I get a pre-signed url it works but it's not convenient.

I try to follow [this][1]  but I can't do it at all. I think the problem comes from the configuration file at the end, I don't know exactly what is needed or not. Knowing that we do not have a connection by google, I would just like to use our aws identifiers. When i click on login on igv and add my longin and password i receive a "succes" answer; but then nothing happen on igv, the menu "amazon --> Load from s3 bucket is still inaccessible.

i use this json (i replace the XXXX by the corresponding value): 

  

       {
       "apiKey": "",

       "project_id": "igv",
    
       "auth_provider": "Amazon",
       "aws_region": "us-east-1",
       "scope": "email",
       "redirect_uris": [
         "http://localhost:60151/oauthCallback"
       ],
    
       "client_id": "XXXXXX",
       "client_secret": "XXXXX",
       "authorization_endpoint": "XXXXXX",
       "token_endpoint": "XXXX",
       "aws_cognito_pool_id": "XXXX",
       "aws_cognito_fed_pool_id": "",
       "aws_cognito_role_arn": "XXXXX"
    }

if people come across this post here is some new information:

The last version of igv (2.13.0) add a native support for s3. You just have to get your credentials (programmatic acces) acces key and secret Key, put your credentials files in the good directory (usually it's ~/.aws/credentials ) and now you can click on the Amazon tab in IGV to load your files.
