Custom Track of Small Exons and Introns
Custom track: Hg18 small exons and introns on the UCSC Genes track
These are exons of size less than 22 bases, and introns of size less than 12 bases. The score column contains the size and thus you can filter smaller subsets via the score column in the table browser.
These small exons and introns are used to maintain frame coding boundaries as found in mRNAs compared to the reference genome coordinates.

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
