Reported comparison
The comparison table this method’s own papers print, standardised: every value on a 0-1 scale, methods down the side, the measure and then the species across. These are numbers papers report about themselves and their baselines. They are not a leaderboard, and they do not compare across tables: each was produced by a different group, on the dataset named in its corner, with each baseline either retrained, run from released weights or quoted from another paper. Where the paper says which, it follows the method’s name (hover it for the sentence); most papers do not say. Bold is the best value in a column and underline the runner-up, our ranking rather than the paper’s own marks.

‡ Not printed in the paper: computed from the differences it prints, as described under the table.
The original table prints only TSARseqNovo's scores, each followed by two 'vs' rows giving its improvement in percentage points over CasaNovo and pi-HelixNovo. The CasaNovo and pi-HelixNovo values here are computed as TSARseqNovo minus that improvement; they are not printed in the paper. The table also misspells pi-HelixNovo as 'pi-HelexiNovo'.
Compared against in other papers (1)
1 table from 1 paper that report this method as a baseline, newest first. The caveats of the comparisons above hold twice over: each paper ran, retrained or quoted this method its own way, so its number here is that paper’s claim, not a measurement of the method. Where a paper says which it did, the word follows the method’s name.
