Description
〔1〕空間的な近さの概念を用いた生体分子データの3次元構造の再構成方法であって、生体分子の一次配列を時間軸と見立てることにより、前記生体分子のHi−Cデータからリカレンスプロットを生成するステップと、前記リカレンスプロットの任意の2つの頂点間の距離を与える距離行列を生成するステップと、前記距離行列に対して多次元尺度構成法を用いて時系列データを再構成するステップと、再構成された前記時系列データから前記生体分子の3次元構造を再構成するステップとを含むことを特徴とする。
ここで、Gi はi行目のリカレンスプロットに打たれている点に対応する時間点の集合であり、|A|は集合Aの要素数を表す。次に、このグラフ上の任意の2つの頂点間の最短路を求める。これは、例えば、ダイクストラ法(上記非特許文献9参照)などを用いると簡単にできる。そして、任意の2つの頂点間の距離が与えられる距離行列を得る。この距離行列に対して、多次元尺度構成法を用いると、元の時系列データの概形を再現するような時系列データが再構成できる。
