General Discussion / ddG LogoGenerator
« on: July 12, 2019, 11:13:01 am »
'm curious about the math behind PWM logos with ddG on the y axis.

Specifically, []The Human Transcription Factors[/] PWM logos were generated via the REDUCE LogoGenerator, so they tell me. They have figures like this (image attached).

The LogoGenerator docs suggest I need a PSAM file or multiple sequence alignment to generate this kind of plot, but all I have is a PWM for each transcription factor.

Is it possible to generate a figure like the one above directly from a PWM? Could you point me towards a reference describing how to do this (mathematically)?

Many thanks,
