Cuffmerge error coultn't finda data file for Mt or Pt?
I'm tring to merge my transcript data produced from 8 samples analysed using TopHat and compiled using Cufflinks. Unfortunately when i run cuffmerge I get an error message about "missing fasta data files for 'Mt' and 'Pt'" but can't find reference to these files anywhere else in the literature or on-line?
Any advice greatfully received. richard@ubuntu:~/RNA_seq_analysis/Cuffmerge$ cuffmerge -g arabidopsis_thaliana.TAIR10.60.gtf -s TAIR10_chr_all.fas -p 6 run297_transcript_cuffmerge.txt [Thu Aug 9 15:36:29 2012] Beginning transcriptome assembly merge ------------------------------------------- [Thu Aug 9 15:36:29 2012] Preparing output location ./merged_asm/ [Thu Aug 9 15:36:36 2012] Converting GTF files to SAM [15:36:36] Loading reference annotation.

Richard,
This is most likely caused by a mismatch between the reference names between the fasta file and the gtf file you are using. The official TAIR10 genome sequence release names the mitochondrial and plastid (chloroplast) chromsomes ChrM and ChrC respectively. These are the names used in TAIR10_chr_all.fas. It would appear that your reference GTF file, arabidopsis_thaliana.TAIR10.60.gtf, is from a different source and uses different names (Mt and Pt). You will need to make sure the chromosome names match exactly between your FASTA and GTF files. |

Thanks for the swift response (again)
 Your advice worked perfectly, i searched the directories near where i downloaded the TAIR10.fasta file and found a TAIR10_GFF3_genes.gff file. The following script appears to be working, but whats the difference between a GFF and GTF file? cuffmerge -g TAIR10_GFF3_genes -s TAIR10_chr_all.fas -p 6 run297_transcript_cuffmerge.txt |

I've found a TAIR10_GFF file (ftp://ftp.arabidopsis.org/home/tair/...enome_release/) which was also near the location where i downloaded my genome fasta file (ftp://ftp.arabidopsis.org/home/tair/...omosome_files/) and one was able to completed the alignment!
Thanks for your help! |

Shouldn't the cuffmerge out put have the gene names (Arabidopsis ATG codes?). What methods are there for adding your genome annotation, i thought that was the reason for using the GFF/gtf files during TopHat and/or cuffmerge?

I used the pipeline that was made in the CyVerse Discovery environment. It's easy to use and really fast!

They have the HTprocess and Kalisto if you're in a rush

Cuffmerge output
I am trying to execute Cuffmerge (cuffmerge -p 5 -g Homo.gtf assemblies.txt), but unable to get FPKM values in output file ("merged.gtf).
Please let me know how to solve this problem.

Please let me know about how "Cuffdiff -L" [-L/--labels: comma-separated list of condition labels] command works. How it is labeling / merging the bam files.
Thanks
