The database for GRCH 37 for rBLAST
Hello, I am trying to use blast in R. It requires downloading the database to a local file. I'm having trouble finding the database for human genome grch37 (I will settle for grch38 too). I've tried refseq_genomic.242 and human_genomic_transcript, none of it returned the right result.
I've read the Manual for the database but couldn't find more detailed explanations on the exact database I'm looking for. The source where I was looking is ftp://ftp.ncbi.nlm.nih.gov/blast/db
Been stuck on it for a while, any help is appreciated, thanks!

How To Get All Proteins Smaller Than 200 Amino Acids Out Of Ncbi Nr Database?
written by Niek De Klein
You could get the hg19 genome sequence from UCSC here. Uncompress and then
catindividual chromosome files into a single large file. Create blast indexes usingmakeblastdband then use those indexes for your program.Thank you for the suggestion. I was thinking about doing it that way. As it seems difficult to locate the the exact grch37 database the blast website is using, I will use the makeblastdb. Thanks again.
