Log in (top left-hand corner of this web page) to use our Expert Mode features, including batch job submissionInfo icon and One-to-One threadingInfo icon. Registering for this is quick and easy on our Login page Info icon.

You can use "One-to-One Threading" to model your sequence against your own in-house structures and those from the Protein Data BankInfo icon, as well as models downloaded from the AlphaFold Protein Structure DatabaseInfo icon.

If you have more than 5 or 6 sequences to model, it is easier for you (and better for everyone!) if you use "batch" processing (under Expert Mode).

Please do not use "intensive mode" unless your search using "normal mode" indicates that a single model does not cover most of your sequence. Info icon For most users, most of the time, 'normal mode' will give you the answer you require in a fraction of the time.
