Bioinformatics operators

5 operators in the bioinformatics category of the live registry. Compose them in a contract or call POST /api/zeq/computeKO42 is always on, plus up to three more per call.

How it computes: dedicated closed-form solver solveStructural — real equations over CODATA-2018 constants; where an operator needs a series/matrix/field a scalar cannot express, it refuses honestly. See the solvers.

OperatorDescriptionEquation
BIO_BLAST_EVALUEBLAST E-value estimating the expected number of alignments with score at least S occurring by chance in a database search.E = K \cdot m \cdot n \cdot e^{-\lambda S}
BIO_GC_CONTENTGC content ratio measuring the proportion of guanine and cytosine bases in a DNA or RNA sequence.\text{GC} = \frac{n_G + n_C}{n_A + n_T + n_G + n_C} \times 100\%
BIO_HIDDEN_MARKOVHidden Markov Model forward probability for gene prediction and sequence annotation in computational genomics.\alpha_t(j) = \sum_{i=1}^{N} \alpha_{t-1}(i) \cdot a_{ij} \cdot b_j(o_t)
BIO_PHYLO_DISTJukes-Cantor evolutionary distance model estimating the number of nucleotide substitutions per site between two DNA sequences.d = -\frac{3}{4} \ln\left(1 - \frac{4}{3}p\right)
BIO_SEQ_ALIGNSmith-Waterman local sequence alignment score for finding optimal local alignments between two biological sequences.H(i,j) = \max\{0, H(i-1,j-1)+s(a_i,b_j), H(i-1,j)-d, H(i,j-1)-d\}

Compute one — a real call

Ask the operator which inputs it needs (the honesty contract refuses empty inputs rather than inventing them):

curl -sS -X POST https://zeqsdk.com/api/zeq/operator-spec \
-H "Content-Type: application/json" \
-d '{"operator":"BIO_BLAST_EVALUE"}'
