\title{Split fasta file into smaller files.}

\usage{

split_fasta(

  path_input,

  target_folder,

  split_n = 500,

  shuffle_entries = TRUE,

  delete_input = FALSE

)

}

\arguments{

\item{path_input}{Fasta file to split into smaller files}

\item{target_folder}{Directory for output.}

\item{split_n}{Maximum number of entries to use in smaller file.}

\item{shuffle_entries}{Whether to shuffle fasta entries before split.}

\item{delete_input}{Whether to delete the original file.}

}

\value{

None. Writes files to output.

}

\description{

Returns smaller files with same file name and "_x" (where x is an integer). For example,

assume we have input file called "abc.fasta" with 100 entries and \code{split_n = 50}. Function will

create two files called "abc_1.fasta" and "abc_2.fasta" in \code{target_path}.

}

\examples{

path_input <- tempfile(fileext = '.fasta')

create_dummy_data(file_path = path_input,

                  num_files = 1,

                  write_to_file_path = TRUE,

                  seq_length = 7,

                  num_seq = 25,

                  vocabulary = c("a", "c", "g", "t"))

target_folder <- tempfile()

dir.create(target_folder)

# split 25 entries into 5 files

split_fasta(path_input = path_input,

            target_folder = target_folder,

            split_n = 5)

length(list.files(target_folder))
