I have gene file in this format, everything in one column (no spaces at all): SFTPB|NM_000542.1|4506904|surfactant, pulmonary-associated protein B Is there any way to convert it in this format (into four columns) except manually? SFTPB NM_000542.1 4506904 surfactant, pulmonary-associated protein B Any suggestions?

Functions like Search allow you to obtain the position of a particulat character (like "|") and knowing that you can select the text to the left or right to it... if you do that consecutively you can sort it like that. It'll take a minute.

For using strsplit in this way, you can also pass the fixed=TRUE option and then you do not need to do any escaping. + seth

If you want to do this in R, the function you want is strsplit, telling it to split on the "|" character. However "|" is special in character splitting (regular expressions) so we have to protect it with backslashes. As a word of advice look up regular expressions - they are extremely powerful for manipulating strings (?regexp) > geneName <- "SFTPB|NM_000542.1|4506904|surfactant, pulmonary-associated protein B" > strsplit(geneName,"\|") [[1]] [1] "SFTPB" "NM_000542.1" [3] "4506904" "surfactant, pulmonary-associated protein B" note it returns a list, where you probably want a vector or array, so something like t(as.matrix(strsplit(geneName,"\|")[[1]])) or unlist(strsplit(geneName,"\|") will give "SFTPB" "NM_000542.1" "4506904" "surfactant, pulmonary-associated protein B" Now lets assume you have a vector of genenames to be split, you can use the sapply function. geneNames <- rep(geneName,3) geneNamesAsMatrix <- t(sapply(geneNames,function(x){unlist(strsplit(x,"\|"))})) > rownames(geneNamesAsMatrix) <- NULL ## otherwise whole str is the row name > geneNamesAsMatrix [,1] [,2] [,3] [,4] [1,] "SFTPB" "NM_000542.1" "4506904" "surfactant, pulmonary-associated protein B" [2,] "SFTPB" "NM_000542.1" "4506904" "surfactant, pulmonary-associated protein B" [3,] "SFTPB" "NM_000542.1" "4506904" "surfactant, pulmonary-associated protein B" Of course you could do this on the command line with perl using something like perl -ne 'my @F=split /\|/,$_;print join("\t", at F)' infile > outfile Cheers Chris >Date: Sun, 06 Nov 2005 02:13:39 +0000 >From: J.delasHeras at ed.ac.uk >Subject: Re: [BioC] Gene names >To: bioconductor at stat.math.ethz.ch >Message-ID: <20051106021339.3x6viekhogs0w8w0 at www.staffmail.ed.ac.uk> >Content-Type: text/plain; charset=ISO-8859-1; format="flowed" > >Quoting Narendra Kaushik <kaushiknk at="" cardiff.ac.uk="">: > > > >>I have gene file in this format, everything in one column (no spaces at all): >>SFTPB|NM_000542.1|4506904|surfactant, pulmonary-associated protein B >>Is there any way to convert it in this format (into four columns) except >>manually? >> >>SFTPB NM_000542.1 4506904 >>surfactant, pulmonary-associated protein B >> >>Any suggestions? >> >>Narendra >> >> > >Maybe too obvious, but Excel is very good for this sort of thing. >Functions like >Search allow you to obtain the position of a particulat character (like >"|") and >knowing that you can select the text to the left or right to it... if you do >that consecutively you can sort it like that.
