Saving image file?

[cossio]

Is it possible to specify an output filename (e.g. png) to save the plot?

Sorry, I didn't see this in my flood of emails. Yes, you can save it if you define a filename parameter when you use seqlogo.seqlogo()

Here is an example:

$ mkdir example
$ cd example

import numpy as np
import pandas as pd
import seqlogo as sl

# Setting seed for demonstration purposes
np.random.seed(42)

# Making a fake PWM
random_ppm = np.random.dirichlet(np.ones(4), size=6)
ppm = sl.Ppm(random_ppm)
>>> sl.seqlogo(ppm, ic_scale = False, format = 'svg', size = 'medium')

$ ls

# Setting seed for demonstration purposes
np.random.seed(42)

# Making a fake PWM
random_ppm = np.random.dirichlet(np.ones(4), size=6)
ppm = sl.Ppm(random_ppm)
sl.seqlogo(ppm, ic_scale = False, format = 'svg', size = 'medium', filename = 'example.svg')

$ ls
example.svg
