Documentation is available
Nomad (Neighborhood Optimization for Multiple Alignment Discovery) is a program dedicated to the ungapped local multiple alignment (ULMA) problem, also known as "blocks". By using an entropy-based objective function that takes into account the amino acid's nature, Nomad is well suited to deal with protein sequences. This objective function, the shared entropy, has been shown to be significantly more reliable than the relative entropy when protein sequences to be aligned are distantly related.
Please fill out the following form, then press the Run Nomad button.

Paste FASTA sequences:
Or upload file

Sequences type:
protein sequences (shared entropy)
protein sequences (relative entropy)
DNA sequences (relative entropy)

Width of the alignment

Occurrences distribution constrains (see documentation):
OOPS (One Occurrence Per Sequence)
ALOOPS (At Least One Occurrence Per Sequence)
AMOOPS (At Most One Occurrence Per Sequence)
AOPS (Any number of Occurrences Per Sequence)
Total number of occurences (required for the ALOOPS, AMOOPS and AOPS constrains)

sort the occurrences by the log-odd score
