get_gt_sequences: Get genome and transcriptome sequences
In TAPseq: Targeted scRNA-seq primer design for TAP-seq

Get DNA sequences of all chromosomes and all annotated transcripts of a genome. This function is used to create the sequences in createBLASTDb.

get_gt_sequences(
  genome,
  annot = NULL,
  tx_id = "transcript_id",
  tx_name = "transcript_name",
  gene_name = "gene_name",
  gene_id = "gene_id",
  include_genome = TRUE,
  standard_chromosomes = TRUE
)

`genome`	A `BSgenome` (or `DNAStringSet`) object containing the chromosome sequences to obtain genome and / or transcript sequences.
`annot`	A `GRanges` object containing all exons of transcripts to be considered. If not specified, no transcript sequences will be included in the output fasta file.
`tx_id, tx_name, gene_name, gene_id`	(character) Column names in annot metadata containing transcript id, transcript name, gene name and gene id information. These column are mandatory, but can contain internal names (e.g. "transcript-1" or "gene-1").
`include_genome`	(logical) Specifies whether the genome sequence should be included in the output fasta file.
`standard_chromosomes`	(logical) Specifies whether only standard chromosomes should be included in output genome sequences (e.g. chr1-22, chrX, chrY, chrM for homo sapiens).
`compress`	(logical) Create a gzipped output fasta file.
