The GC percent track shows the percentage of G (guanine) and C (cytosine) bases in 5-base windows on the 06 Jul 2026 Mesoplodon mirus/GCF_964341445.2_mMesMir1.hap1.2/GCF_964341445.2 genome assembly. High GC content is typically associated with gene-rich areas. The average overall GC percent for the entire assembly is % 42.45.
This track may be configured in a variety of ways to highlight different aspects of the displayed information. Click the "Graph configuration help" link for an explanation of the configuration options.
This track is generated on-the-fly by the browser as needed up
to a data density of 50,000 bases per pixel display. Greater than that display
density and the display transitions to using the bigWig file:

You can extract the data from that file with the
kent command line program: bigWigToWig:

| gzip -c > GCF_964341445.2.gcOnFly.varStep.gz
That bigWig data was calculated with the hgGcPercent command
with the window size of -win=50000.
To obtain the traditional 5-base window data for this track
use the following kent command line program hgGcPercent:
hgGcPercent -wigOut -doGaps -file=stdout -win=5 -verbose=0 test \
