proftmb 1.1.12-3 (armhf binary) in ubuntu xenial

 proftmb predicts transmembrane beta-barrel (TMB) proteins in Gram-negative
 bacteria.
 .
 For each query protein, proftmb provides both a Z-value indicating that the
 protein actually contains a membrane barrel, and a four-state per-residue
 labeling of upward- and downward-facing strands, periplasmic hairpins and
 extracellular loops.
