Custom Xlabels

[pguillem]

Hi. I'm doing a protein logo with mutations, and I need to make the Xlabel show the wildtype and number, instead of only the number.

This is my 'logo' dataframe

When doing the figure, it complains:

fig = logomaker.Logo(logo)

logomaker.src.error_handling.LogomakerError: could not convert df.index to type int. Check that all positions have integer numerical values.

Thanks in advance

Can you provide a minimal working code snippet for me to reproduce your issue?

[pguillem]

Thank you @atareen
I believe the first column of the dataframe is expected to be an integer, instead of a string. Weblogos usually just display the position number, but in this case scenario the desired Xlabel of the logo would be the notation "Residue+Position".

This is the code I'm using to try it:

import pandas as pd
import logomaker

 #logodict is the dictionary to create the dataframe on top
logo = pd.DataFrame(logdict)
fig    = logomaker.Logo(logo)

If you provide the data in a file, I'll plot the logo for you and share the code.

I've plotted a logo from the data you've provided along with your custom xlabels from the first column of data. I am attaching a screenshot of a very minimal example showing this, but please note this is not a logomaker issue, so I am closing this.
