vcontact2 failure when no cluster found

vcontact2 failure when no cluster found, see
[mcl] jury pruning marks: <100,100,100>, out of 100
[mcl] jury pruning synopsis: <100.0 or really really really good> (cf -scheme, -do log)
[mcl] output is in vConTACT2_Results/merged.self-diamond.tab_mcl20.clusters
[mcl] 0 clusters found

INFO:vcontact2: Building the cluster and profiles (this may take some time...)
If it fails, try re-running using --blast-fp flag and specifiying merged.self-diamond.tab (or merged.self-blastp.tab)
