Get Similarity Scores Hits of Proteins in a Species
Using this function, you can retrieve the Smith-Waterman bit scores among proteins of the same species. Bit Scores serve as similarity scores between protein sequence; And, according to STRING documentations, as a proxy for protein homology.
rba_string_homology_intra(ids, species = NA, ...)
ids |
Your protein ID(s). It is strongly recommended to provide
STRING IDs. See |
species |
Numeric: NCBI Taxonomy identifier; Human Taxonomy ID is 9606. (Recommended, but optional if your input is less than 100 IDs.) |

rbioapi option(s). Refer to |
Note that this function will retrieve similarity scores of different
proteins "within the same species". To Get a similarity scores of a given
protein and it's closets homologous proteins in other species, refer to
rba_string_homology_inter.
Similarity matrix is imported -by STRING- from:
Similarity Matrix of
Proteins (SIMAP)
A data frame with bit scores between your provided proteins and their self-hit. To Reduce the transferred data, STRING returns only one half of the similarity matrix; This will not pose a problem because similarity matrix is symmetrical.
