Methods
- From the table browser, request three different bed files for the knownGenes track:
- whole gene
- exons only
- introns only
- From those bed files, stats can be extracted
- gene count from: 'wc -l wholeGene.bed'
- exon count stats from:
STATS=`ave -col=10 wholeGene.bed -tableOut | grep -v "^#"`
MIN=`echo $STATS | cut -d' ' -f1`
MAX=`echo $STATS | cut -d' ' -f5`
MEAN=`echo $STATS | cut -d' ' -f6 | awk '{printf "%d", $1+0.5}'`
COUNT=`echo $STATS | cut -d' ' -f8 | awk '{printf "%d", $1}'`
- for exon or intron size stats:
STATS=`awk '{print $3-$2}' {introns,exons}.bed \
| ave -col=1 stdin -tableOut | grep -v "^#"`
MIN=`echo $STATS | cut -d' ' -f1`
MAX=`echo $STATS | cut -d' ' -f5 | awk '{printf "%d", $1}'`
MEAN=`echo $STATS | cut -d' ' -f6 | awk '{printf "%d", $1+0.5}'`
SUM_SIZE=`awk '{sum += $3-$2} END{printf "%d", sum}' {introns,exons}.bed`
- top five exon count genes
sort -k10nr wholeGene.bed | head -5
- top five CDS size genes
awk '{cdsSize=$8-$7
if (cdsSize > 0) {printf "%s\t%s\t%s\t%s\t%d\n", $1,$2,$3,$4,cdsSize}
}' wholeGene.bed | sort -k5nr | head -5
- top five smallest transcript genes
awk '{size=$3-$2
if (size > 0) {printf "%s\t%s\t%s\t%s\t%d\n", $1,$2,$3,$4,size}
}' wholeGene.bed | sort -k5n | head -5
