The phrase "a supplementary alignment" is correct and usable in written English.
It can be used in contexts where additional alignment or adjustment is needed, often in technical, academic, or organizational discussions.
Example: "The team proposed a supplementary alignment to ensure that all project goals were met effectively."
Alternatives: "an additional alignment" or "a complementary alignment".
The supplementary alignment (S2) only shows one Tlr protein (which one is it?).
The alignment consisted of 538 nt coding for 179 amino acids using the invertebrate mitochondrial code (Supplementary Alignment A1).

This significantly altered the length of the array as well as the species-specific consensus sequence (see fig. 3 C and supplementary alignment S2, Supplementary Material online).
All putative H. annosum SNPs/InDels detected by comparative sequence analysis of the six genomes were confirmed in the genotypes for which individual loci were sequenced (see supplementary alignment S1, Supplementary Material online).
With the exception of the Chinese tree shrew (which had an additional duplication, supplementary fig. S2, Supplementary Material online), all placental mammals share the human array topology (see supplementary alignment S4, Supplementary Material online), which was therefore likely part of their common ancestor (∼65 Ma O'Learyry et al. 2013 ).
Manual inspection of the corresponding alignments (Fig. 5; Supplementary Alignment S1 Supplementary Table 3) showed that one co-ortholog of DRS2 (Solyc01g011100) has a shorter N-terminal domain; one FAP7 co-ortholog (Solyc06g075310) lacks the C-terminal region; and the co-orthologs of MDN1 (Solyc04g072270) and YAR1 (Solyc04g008580) represent only a short fragment.

The amino acid sequences of 163 vertebrate globins were used to construct a multiple sequence alignment (supplementary table S5, Supplementary Material online).
