I have run cuffDiff on my data. The out put of the cuffdiff is in a directory named "tx_win_cuffdiff_output". I am trying to analyse it in cummeRbund. The system and R information is as follows:

> platform       x86_64-w64-mingw32          
arch           x86_64                      
os             mingw32

version.string R version 3.4.2 (2017-09-28)
nickname       Short Summer

I ran the following command after loading cummeRbund library

> (cummeRbund)
cuff <- readCufflinks(dbFile = "cuffData.db", dir="tx_win_cuffdiff_output", gtfFile = "tx_win_cuffdiff_output/transcripts.gtf", genome = "tx_win_cuffdiff_output/SuperDuper.fasta.fasta",rebuild =T)

Following error is shown:

     Creating database tx_win_cuffdiff_output/cuffData.db 
Reading Run Info File tx_win_cuffdiff_output/run.info
Writing runInfo Table
Reading Read Group Info  tx_win_cuffdiff_output/read_groups.info

Error: Column name mismatch.
In addition: There were 50 or more warnings (use warnings() to see the first 50)

Where did I erred.

Thanks

You should know that the old 'Tuxedo' pipeline of Tophat and Cufflinks is no longer the "advisable" tool for RNA-seq analysis. The software is deprecated/ in low maintenance and should be replaced by HISAT2, StringTie and ballgown. See this paper: Transcript-level expression analysis of RNA-seq experiments with HISAT, StringTie and Ballgown. (If you can't get access to that publication, let me know and I'll -cough- help you.) There are also other alternatives, including alignment with STAR and bbmap, or pseudo-alignment using salmon.

I added markup to your post for increased readability. You can do this by selecting the text and clicking the 101010 button. When you compose or edit a post that button is in your toolbar, see image below:
