Approach to better assign genes to peaks

New Approach Idea

Lin et al: An in-depth map of polyadenylation sites in cancer 2012: -Mapped locations to annotated locations in UCUS browser: “The mapped locations were annotated using the UCSC genome browser tables ( 26 ). When a locus could be attributed to multiple possible annotations, the locus was assigned with a single annotation in the following priority order: 3′ UTRs (sense), coding sequences (CDS, sense), 5′ UTRs (sense), intron (sense), non-coding RNAs (ncRNAs, sense), 5′ UTR antisense, CDS antisense, 3′ UTR antisense, intron antisense, promoter antisense, ncRNA antisense and intergenic”

I want to download this annotation and try this. I am using the ncbi_refseq annotations. I will download regions of the genome seperatly and then merge the files.

• 5’ UTR

• Coding Exon

• Intron

• 3’ UTR

• (downstream 5000)-downstream proximal region

I also want a dictionary with the transcripts and the gene names for the annotation. This information will come from the Transcript2GeneName file. In this file the transcript ID is in column1 and the gene name column 13.

I have downloaded all of the these to data/RefSeq_annotations. I will concatinate all of these for a full annotation dataset, I will then sort this file. The file is ncbiRefSeq_allAnnotation.sort.bed

Using this I can create an annotation in a bed file I can use for the overlap with my peaks. This will include getting the transcript to gene annotations. I will transfer the files to midway in my genome annotation directory and work with them there.

Format full refseq annotation:

TXN2Gene_file="/project2/gilad/briana/genome_anotation_data/RefSeq_annotations/Transcript2GeneName.dms"

gene_dic={}

for ln in open(TXN2Gene_file,"r"):
   txn=ln.split()[1]
   gene=ln.split()[12]
   gene_dic[txn]=gene

outF=open("/project2/gilad/briana/genome_anotation_data/RefSeq_annotations/ncbiRefSeq_FormatedallAnnotation.sort.bed","w")

inFile="/project2/gilad/briana/genome_anotation_data/RefSeq_annotations/ncbiRefSeq_allAnnotation.sort.bed"  


for ln in open(inFile, "r"):
   chrom, start, end, name, score, strand = ln.split()
   chrom_fix=chrom[3:]
   txn=name.split("_")[:2]
   txnF="_".join(txn)
   gene=gene_dic[txnF]
   type=name.split("_")[2]
   id=type + ":" + gene
   outF.write("%s\t%s\t%s\t%s\t%s\t%s\n"%(chrom_fix, start, end, id, score, strand))

outF.close()

Map peaks with new annotation

I want to create a file with my peaks mapped to these regions. I will include a structure for when there is a tie and put intergenic if it is not found. I need to do an intersect that gives me all of the IDs. After this I can use python to parse the hiarchy.

I can use bedtools map for this. I want all of the data to come back.

-c 4 -o distinct
-S opposite strand

I will do this on the peaks before I looked at usage.

bedtools map -a /project2/gilad/briana/threeprimeseq/data/mergedPeaks_noMP_filtered/Filtered_APApeaks_merged_allchrom_noMP.sort.named.noCHR.bed -b /project2/gilad/briana/genome_anotation_data/RefSeq_annotations/ncbiRefSeq_FormatedallAnnotation.sort.bed -c 4 -S -o distinct > /project2/gilad/briana/threeprimeseq/data/mergedPeaks_noMP_GeneLoc/Filtered_APApeaks_merged_allchrom_noMP.sort.named.noCHR_geneLoc.bed

Look at how many get no annotation. I can do this interactively in python.

num=0
for ln in open("/project2/gilad/briana/threeprimeseq/data/mergedPeaks_noMP_GeneLoc/Filtered_APApeaks_merged_allchrom_noMP.sort.named.noCHR_geneLoc.bed", "r"):
    location=ln.split()[7]
    if location==".":
        num +=1

print(num)

This shows me that 85% of the peaks fall into one of these annotations.

Now I need to sort out the peaks with multiple annotations.

4. 5’ UTR

5. Coding Exon

6. Intron

7. 3’ UTR

8. (downstream 5000)-downstream proximal region

I can write this out as the SAF I need. GeneID (peak1:1:14404:14484:-:OR4F16) Chr Start End Strand. For this I cannot include the peaks with no gene association. I can go back to this if i need to in the future.

Map reads to new annotated peaks

This has all of the peaks with at least one gene annotation. (104555) I can run feature counts on this to start getting the usage.

Genes covered with these annoations.

#nuclear
nrow(NuclearPeakUSMean_filt) 

[1] 14851

#total
nrow(TotalPeakUSMean_filt) 

[1] 14852

There are more genes in this. We expect this because i have included LINCs.

Look at number of peaks in each set.

#nuclear  
NuclearPeakUSMean %>% filter(nuclearPeakUs_CountNum_mean>=.05) %>% nrow()

[1] 37370

#total
TotalPeakUSMean %>% filter(totalPeakUs_CountNum_mean>=.05) %>% nrow()

[1] 33002

There are a few less peaks. This is expected give we cut 15% of the peaks because they are not within 5kb of an annotated gene.

Write out these peaks

NuclearPeakUSMean_5perc=NuclearPeakUSMean %>% filter(nuclearPeakUs_CountNum_mean>=.05)
write.table(NuclearPeakUSMean_5perc,file="../data/PeakUsage_noMP_GeneLocAnno/filtered_APApeaks_merged_allchrom_refseqGenes.GeneLocAnno.NoMP_sm_quant.Nuclear_fixed.pheno.5percPeaks.txt", row.names=F, col.names=F, quote = F)

I want to filter these peaks so I can rerun the leafcutter analysis and look at some of the results. I transfered these to /project2/gilad/briana/threeprimeseq/data/phenotypes_filtPeakTranscript_noMP_GeneLocAnno/.

Diff Iso in leafcutter

Now I can use these peaks to get counts for leafcutter.

I want a file that will have the peaks from total or nuclear.

I am starting here with the SAF file

    peaknum=peakname[4:]
    allPeakOk[peaknum]=""

    peaknum=peakname[4:]
    if peaknum not in allPeakOk.keys():

        if peak_num in allPeakOk.keys():
             outFile.write(ln)
outFile.close()
    

Now I will run feature counts, remembering that i want to look at the same strand as the peaks.
