2022-12-20 10:30:34 - INFO - Input is not mean-centered, setting the mean of all rows to 0.

2022-12-20 10:30:34 - INFO - Note that if you use count data (ChIP-seq, ATAC-seq) we recommend to first transform your data, for instance using log2(), and to normalize between samples. To create a table suitable for maelstrom you can use the coverage_table script included with GimmeMotifs.
