Converts a frequency matrix to a weight matrix. Weight matrices are used for probabilistic recognition of transcription factor binding sites.
Element type: fmatrix-to-wmatrix
Parameters
| Parameter | Description | Default value | Parameter in Workflow File | Type |
|---|---|---|---|---|
| Matrix type (required) | Dinucleic matrices are more detailed, while mononucleic one is more useful for small input data sets. | Mononucleic | type | boolean Available values are:
|
| Weight algorithm | Different weight algorithms use different functions to build weight matrices. It allows us to get better precision on different data sets. Log-odds, NLG and Match algorithms are sensitive to input matrices with zero values, so some of them may not work on those matrices. | Berg and Von Hippel | weight-algorithm | string Available values are:
|
