Input: LIPS requires a multiple sequence alignment of the TM helix in Fasta format with no gaps as an input. Input sample
Output: 1. LIPS outputs sets of residues that compose each of seven helical faces. These are numbered 0 ... 6.
2. LIPS outputs average scores (lipophilicity, entropy and lipophilicity*entropy) for every surface.
The largest LIPS score indicates a probable high lipid exposure of the helical surface. The smallest LIPS score may indicate either a highly buried or a tightly packed helical face.
