I get a funny error (see below), when running dist.shared. When I switch back to 1.36 dist.shared works on the file. Happy to share the input file for you to sort it out/replicate error if interested. I am running a fully patched Ubuntu 16.04.2 LTS and mothur 1.39.5. Looks like something with glibc
mothur > dist.shared(shared=stability.trim.contigs.good.unique.good.filter.unique.precluster.pick.pick.pick.opti_mcc.shared, calc=jclass-braycurtis, subsample=T, label=0,processors=4)
Using 4 processors.
