RADICAL stands for Random Addition Concatenation Analysis. It concatenates randomly selected gene partitions and builds phylogenetic trees (MP with PAUP*/ML with RAxML) to examine tree-to-tree agreement of the concatenation path. Also calculates ML support per node and partition. See Narechania et al. (2011 Genome Biol Evol).
The radical/0.2 code is preset for using 2 RAxML threads, so the batch job resource request must be in the form of "nodes=1:ppn=2". There is no PAUP option.
