note - we currently only support immunoglobulin (IG / B cell receptor / antibody) sequence curation
your antigen receptor sequences provide up to 50 FASTA-formatted or tab-delimited (ID[tab]sequence e.g. copy-paste from Excel) nucleotide sequences - ~100kb upload limit

your permission We may look at your data to improve what we do for all users including you, nothing more - you can:
disagree, in which case we guarantee we'll ignore your data,
agree, in which case and if you want us to be able to contact you with questions, feedback or corrections,
            you can leave your name and/or e-mail here: namee-mail
In any case, please make sure you provide uninformative/anonymous IDs for your sequences.

DISCLAIMER - there is no guarantee that ARResT/SeqCure will be able to capture all the issues with your sequences, please bear this in mind when making decisions, especially important ones on e.g. clinical care. To help us improve ARResT/SeqCure, consider permitting us to look at your data through the form, or get in touch on your own.

background and instructions

| intro
ARResT/SeqCure is based on an expandable knowledgebase and set of rules that are able to capture, describe, and advise on issues with the input sequences. This output can then be used to curate the sequences to allow for higher quality analysis.

| input formats
Input is antigen receptor nucleotide sequences, in either FASTA format or tab-delimited. Sequence ID will be cut at first ';' (and still finally truncated to 49 characters at IMGT)


We have enabled the use of the tab key in the textbox above, but the tab-delimited format is mainly provided for simply copy-pasting such information from a spreadsheet (e.g. Excel).

| progress
When you are ready click on 'submit to ARResT/SeqCure'. The page will change to keep you informed of our progress. This includes a preliminary table of colour-coded alarm levels and counts of issues with your sequences (more on this below). ARResT/SeqCure has two main stages which again you can follow here, primary and advanced, the latter based on running IMGT/V-QUEST, twice if necessary to confirm a potential insertion or deletion (indel). In the end, provided that everything went smoothly, you will be provided with a link to see the full report.

| output / report
The report section provides messages generated by ARResT/SeqCure, including the sequence ID and index/order (from zero) and the stage in which it was generated ('pri' for primary analysis, 'round 1' and 'round 2' for advanced IMGT/V-QUEST-based analysis, without and with the indel option activated, respectively).

The advice section provides additional information for the reported issues and very often a link to comprehensive text below. The numbers in {} delineate the different advice and are for internal use, please ignore them for now.
