Dear Pathview and Clusterprofiler developers,

During a submission process of a manuscript, which includes KEGG figures produced by via pathview (based on the functional enrichment results found using Clusterprofiler and Goseq) we are specifically asked to provide a permission for the usage of the figures,  since in the figures it is specifically written "Kanehisa Laboratories". Is it a problem, or are these figures free for publication ? 

thanks a lot

Assaf
