genomic_gc3: genomic gc3 for an multifasta genomic file

Description

The function calculates the genomic gc3 for an multifasta genomic CDS file. The function first concatenated all the CDS sequences in the file into one long CDS string, than calculated the gc3 from the GC3 function in seqinr package. You can also use the function to calculate the gc3 for a single gene, or a set of genes, depends what content you put in the input file.

Usage

genomic_gc3(inputfile)

Arguments

inputfile

a character vector for the filepath of the whole genome cds file

Value

• a numeric vector genomic_gc3 is returned

Details

The function calculates the genomic gc3 for an multifasta genomic CDS file. The function first concatenated all the CDS sequences in the file into one long CDS string, than calculated the gc3 from the GC3 function in seqinr package. You can also use the function to calculate the gc3 for a single gene, or a set of genes, depends what content you put in the input file. The result can be used as input for the s_index calculation.
