Reading a file produced by the BLAST+ software set up to produce tabular output.
Name of file to read.
This function will read files produced by the BLAST+ software where the option -outfmt 6
has been invoked during its call. This option forces BLAST to produce a short tabular text output for
each BLAST search. The function
blastAllAll produces such files.
The content of the file is returned as a data.frame with 12 columns and one row for each BLAST result. The columns have self-explanatory names.

# Using a BLAST result file in this package xpth <- file.path(path.package("micropan"),"extdata") blast.file <- file.path( xpth, "GID1_vs_GID2.txt.xz" ) # We need to uncompress it first... tf <- tempfile(fileext=".xz") s <- file.copy(blast.file,tf) tf <- xzuncompress(tf) #...then we can read it... blast.table <- readBlastTable(tf) # ...and deleting temporary file s <- file.remove(tf)
