Enter the file containing your sequence or aligned sequences for uploading. The sequences must be in FASTA format. Maximum file size is 10kb and maximum alignment length is 2000.

Note: Currently a predicted strucutre will be given for the first sequence in the alignment only!

Or input the actual sequence here (in FASTA format):

Options for generating score matrix:

Ratio of mutual information score and (extended) helix plot score: :

Use extended helix plot score (Strongly recommended for single sequences).

Folding algorithm: Iterated Loop Matching Maximum Weighted Matching

Options for iterated loop matching:

Minimum loop length (L): Minimum virtual loop length (V):

Minimum helix length (H): Number of helices per iteration (N):

Number of iterations before stop (I):
