Af1#
This page provides a curated list of functions and properties available in the malariagen_data
API
for data on mosquitoes from the Anopheles funestus subgroup.
To set up the API, use the following code:
import malariagen_data
af1 = malariagen_data.Af1()
All the functions below can then be accessed as methods on the af1
object. E.g., to call the
sample_metadata()
function, do:
df_samples = af1.sample_metadata()
For more information about the data and terms of use, please see the MalariaGEN Anopheles funestus genomic surveillance project home page.
