Tracer summarise output

[YarsnC]

Hi!

Thanks a lot for this wonderful work!

My colleague did some analysis using tracer and we're a little bit confused about the output file 'cell_data.csv' and 'recombinants.txt'. It seems that some cells are not mentioned in these two files. (No 'No seqs found for TCR_['A', 'B', 'G', 'D']' message for these cells in recombinants.txt either). According to the filtered_TCRs.txt file of some of these cells I checked, they do have recombinants successfully assembled.

I'm wondering if these cells are filtered somewhere? Did I miss something?

Best,

Dana

Hi. Please could you send some examples of outputs that are discordant like this. I can then start to explore what’s going on. Thanks! Mike

Hi, These cells all look like they might be MAIT cells (they have a TRAJ1-2-to-TRAJ33 alpha chain) and so are filtered out by TraCeR to avoid the appearance of expanded clonotypes that are less likely to be interesting. Please can you check a couple of things: 1. If you look in `TCR_summary.txt` you should see these cells reported as potential MAIT cells at the bottom. 2. If you run `summarise` with the `--keep_invariant` option it should now report these cells in `cell_data.csv` and `recombinants.txt`. Let me know if that helps. This is a nice review on MAIT cells (and other unconventional T cells): https://www.nature.com/articles/ni.3298 <https://www.nature.com/articles/ni.3298> All the best, Mike
