Im trying to run tximport for the DESeq2 pipeline for an Arabidopsis DE analysis and i found this error, first i try with ignoretxversion=TRUE,ignoreafterbar=TRUE and none of those flags works, then i read the tx2gene object to compare it with quants.sf file and i see this:

> head(tx2gene,10)
        TXNAME    GENEID
1  AT1G01010.1 AT1G01010
2  AT1G03987.1 AT1G03987
3  AT1G01040.1 AT1G01040
4  AT1G01040.2 AT1G01040
5    at1g01046 AT1G01046
6  AT1G03997.1 AT1G03997
7  AT1G01110.2 AT1G01110
8  AT1G01110.1 AT1G01110
9  AT1G01160.1 AT1G01160
10 AT1G01160.2 AT1G01160

I have done just a few DE analysis, this is my first study in plants, and i havent seen this never (lowercase for some txnames), can be this making the error happen? why the gtf and gff files have this format for some txs? how i solve that, just converting the txsnames to uppercase?

I let the output and session info down Thanks for anyresponse

Here the issue can be easily fixed. ignoreTxVersion is for trimming the version numbers from the quantification files. Here the issue is that you have version numbers in the tx2gene table. All you have to do is chop the version numbers in the table. You can do this with:

chop <- function(x) sub("\\..*","",x)
