Hi everyone. Im an absolutely new guy working in bioinformatics, and i would like if you could help me.

I want to do featurecounts, i think im doing it well but i cant find the output...i was reading that i should expect a kind of table with my data, but i cant find it...do i need an "extra line "?

this is what i did... Thank you in advance

> newcount = featureCounts(files=c("H1_1sorted.bam"), annot.ext="GCF_000524195.1_ASM52419v1_genomic.gff", isGTFAnnotationFile=TRUE, isPairedEnd=TRUE, GTF.attrType="ID")

Looks like you forgot to provide an output file to hold the result table. You would normally provide this with -o <output_file> on command line version. Look for R equivalent.

I have never used the program in R, but I think your reads counts table will be saved in R object newcount. Can you check that object with e.g. head?

head(newcount)

thank you Benn for your answer (and thanks to genomax too). When i write that command , there is a long list and finally sent me a message ...is there any way to export that to an .xls file or something? This is what i get ... thank you!

It is in newcount as you redirected the output to that variable. Please spend some time on the R basics before diving into analysis.

Than you all. I solved it.

as you told, the "newcount" was the name of the new file. And with the command

head(newcount)

im able to see the counts. Now i "printed" the output to a .txt file with

write.table(x=data.frame(newcount$annotation[,c("GeneID","Length")],newcount$counts,stringsAsFactors=FALSE),file="newcount.txt",quote=FALSE,sep="\t",row.names=FALSE)

Thankyou every one for your answers
