INI — Introduction to the Bioinformatics Armory
solved Problem statement
GBK — GenBank Introduction
solved Problem statement
Calls NCBI, so it needs a network connection and its answer can change over time.
Entrez record counts grow as GenBank is updated, so no fixed answer can be asserted.
FRMT — Data Formats
solved Problem statement
Calls NCBI, so it needs a network connection and its answer can change over time.
MEME — New Motif Discovery
partial Problem statement
Partial: no probabilistic motif discovery; finds exact shared substrings instead of a MEME position-weight motif.
NEED — Pairwise Global Alignment
solved Problem statement
Calls NCBI, so it needs a network connection and its answer can change over time.
Reproduces the EMBOSS Needle score of 257 using align() with affine gaps (match 5, mismatch -4, gap_open -9, gap_extend -1). Asserted, but excluded from the hermetic CI gate because it fetches from NCBI.
TFSQ — FASTQ format introduction
solved Problem statement
PHRE — Read Quality Distribution
solved Problem statement
PTRA — Protein Translation
solved Problem statement
FILT — Read Filtration by Quality
solved Problem statement
RVCO — Complementing a Strand of DNA
solved Problem statement
SUBO — Suboptimal Local Alignment
solved Problem statement
Brute-force O(n^3) window scan; ~25 s. A motif-index approach would be the natural follow-up.
BPHR — Base Quality Distribution
solved Problem statement
CLUS — Global Multiple Alignment
solved Problem statement
ORFR — Finding Genes with ORFs
solved Problem statement
BFIL — Base Filtration by Quality
