Helix type: α 3-10 3-11 π Choice the helix type

Window size Choice of the size of the analysis window (one turn correspond to one helical wheel according to the helix type)

Paste your helix sequence:

One-letter code size proportional to amino acid volume yes no

Rotation of the helix to align vertically the <µH> vector yes no


The processing can take from few seconds to several minutes. Please be patient
