    line.break = -1,
    delimiter = "|");

read

load a set of fasta sequence data in lazy mode? default is yes. [as boolean]

line.break

the sequence length in one line of the generated fasta document when this function is used for open a fasta file in write mode, a negative value means that all of the sequence data will be written in a single line. [as integer]

delimiter

the delimiter character for merge the fasta headers title when this function is used for open a fasta file in write mode. [as string]
