Hello everyone, I am new to R and cummeRbund, but I would like to share with you some problems that occurred to me. I'm tryin to build a cufflinks database to analyze which genes are more expressed in IPSc VS normal cells,and I put in my working directory all the files that the company who did the run sent me. First question that I wanted to ask you: which KInd of files I have to put inside the dir? I mean I have two folders:cufflinks and cuff diff,Inside of cufflinks there are 3 files: genes.fpkm_tracking,isoforms.fpkm_tracking,transcripts.gtf and in the cuffdiff there another file called genes.fpkm_tracking and isoforms.fpkm,which one i have to put inside the working directory? Second question: when I try to build the cuffdata.db this the error that comes out: cuff<readCufflinks(genome="Hg38",gtfFile="transcripts.gtf",rebuild=T) Creating database /home/alessio/R/i686-pc-linux-gnu-library/3.2/cuffData.db Reading Run Info File /home/alessio/R/i686-pc-linux-gnu-library/3.2/ Writing runInfo Table Reading Read Group Info /home/alessio/R/i686-pc-linux-gnu-library/3.2/ Writing replicates Table Reading Var Model Info /home/alessio/R/i686-pc-linux-gnu-library/3.2/ Writing varModel Table Reading GTF file Writing GTF features to 'features' table...

These are my session INfos:

Another one is when i Try to build a geneset,this is my error code:

data(sampleData) > myGeneIds<-sampleIDs > myGeneIds [1] "XLOC_001363" "XLOC_001297" "XLOC_001339" "XLOC_000132" "XLOC_001265" [6] "XLOC_000151" "XLOC_001359" "XLOC_000069" "XLOC_000170" "XLOC_000105" [11] "XLOC_001262" "XLOC_001348" "XLOC_001411" "XLOC_001369" "XLOC_000158" [16] "XLOC_001370" "XLOC_001263" "XLOC_000115" "XLOC_000089" "XLOC_001240" > myGenes<-getGenes(cuff,myGeneIds) Getting gene information: FPKM Error in sqliteSendQuery(con, statement, : error in statement: near ")": syntax error

Sorry for the long Thread but I would like really to solve this problem thanks to you. Thank you in advance
