Sometimes we have a few individual sequences we wish to import as single-read contigs. That is we won't align them against each other or against existing data, but just load them into our gap5 database so we can then run tools such as Find Repeats or Find Internal Joins on them. (This can be ideal for importing consensus sequences.)
The "Import Fasta/Fastq as single-read contigs" function is designed
for this purpose. Behind the scenes it is nothing more than running
tg_index -a
to add a fasta or fastq file.
