Expert options: alignment (MaxHom)
USE MaxHom expert options Tick to activate options
IDE = minimal % sequence identity (15 < IDE < 100)
Note: false positives rapidly increase for values < 30%!
Gap open penalty (1 < GO < 50)
Gap extension penalty (1 < GE < 50)
Comparison metric
Maximal hit value (0.5 ≤ SMAX ≤ 50)
Expert options: transmembrane helices (PHDhtm)
USE PHDhtm expert options Tick to activate options
Minimal membrane helix propensity (0 ≤ Phtm ≤ 1)
MIX = 1.0 -> strongest transmembrane helix (HTM) propensity
MIN = 0.5 -> half HTM, half not (will be labelled HTM)
MIN = 0.0 -> anything labelled HTM
Expert options: Ambivalent Sequence Predictor (ASP)
USE ASP expert options Tick to activate options
Window size: (1 < WS < seqLen, odd integer)
z score cutoff: More positive Z-score cutoffs relax the significance requirement
minimum mu dPr score: (0 < MIN < 18, integer)
Expert options: CHOP
USE CHOP expert options Tick to activate options
BLAST e-value:
real number (suggested between 1e-10 to 1)
HMMER E-value:
real number (suggested between 1e-6 to 0.1)
Min domain coverage:
integer between 60 and 99
Min length of domain:
integer between 20 and 60


One-line name of protein (not necessary)

Paste, or type your sequence

  • amino acids in one-letter code
  • any number of white spaces allowed
  • non-standard amino acids to 'X'


  • use SRS6 to get your sequence from a public database
