Hi there! I need to use tximport.

I have some poblems on intallation of this package:

 

 

https://bioconductor.org/install/#troubleshoot-biocinstaller
> biocLite("tximportData")
BioC_mirror: https://bioconductor.org
Using Bioconductor 3.2 (BiocInstaller 1.20.3), R 3.3.0 (2016-05-03).
Installing package(s) ‘tximportData’
Warning message:
package ‘tximportData’ is not available (for R version 3.3.0)

I was able to install tximport but miss some commands..

 

rm(list=ls())

suppressMessages(library( "DESeq" ))
suppressMessages(library("tximport"))

setwd("~/Desktop/Prova_strand")
dir<-"~/Desktop/Prova_strand/"
metadata<-read.table("tipo.csv",header=F)
files=file.path(dir,metadata$V1)
txi.rsem<-tximport(files,type="rsem",reader=read.delim)

sample<-data.frame(condition=factor(c("A","B")))


dds<-DESeqDataSetTxiport(txi.rsem,sample,~1)
Error: could not find function "DESeqDataSetTxiport"

hi, 

This error is because the modeling cannot have transcripts of length zero included in the offset calculation. What does it mean to have a gene of length 0 after all?

I don't know the best solution here, the zeros are being produced by the upstream software, but I've recommended to others to just insert a length of 1 instead for these 0's, before moving on to DESeq2:

txi$length[txi$length == 0] <- 1

tximportData is only available for Bioconductor 3.3. It says here you are using version 3.2.
