File ExchangeにあるJean-Luc GOUDIERのコードは、 前後との差が両方とも正になる部分を探すので、同じ値が続いていると検出出来ないが、 その様なデータは稀であるので、今回はこれを使用する。processfile(filename,50,-10,60)のパラメータが順にピーク検出の正の閾値、負の閾値(ここに負を入れると、 ピークが負で底打ちしていなくても検出する)、時間軸の閾値で、スクリプトと同じフォルダにdataというフォルダを作って、検査CSVデータを入れておけば、 それぞれの検査CSVデータに対して処理した結果をoutフォルダ(自動生成)に出力する。PDFの描画では、ピークの順番に描画を変え、ピーク検出結果をCSVに保存する。
