About Mass++

We have been developing a fast spectrum viewer, Mass++, which has been downloaded about 20000 times to date in total of all releases. The version currently under development is Ver.4, which is open-source software, newly rewritten in the Java language to be compatible with multiple operating systems. This time, we have organized the various functions that have been developed to date and generated a package as the official release of Ver. 4 (Ver.4 Gold), focusing on basic functions, especially those related to the display of spectra and chromatograms, such as zooming of spectra/chromatograms, labeling of peaks, exporting of spectra/chromatograms to image files, and functions to narrow down spectra by m/z values and retention time values. This Ver.4 Gold package will be released in four operating system environments: Windows, MacOS, Linux Debian/Ubuntu, Linux RPM.

私たちは、高速スペクトルビューア「Mass++」を開発し、これまでに全バージョン合計でおよそ2万回のダウンロードを記録してきました。現在開発中のバージョンはVer.4で、オープンソースソフトウェアとして、新たにJava言語で書き直し、複数のOSに対応できるようにしました。今回、これまで開発してきた様々な機能を整理し、Ver.4の正式リリース（Ver.4 Gold）として、基本的な機能、特にスペクトルやクロマトグラムの表示に関する機能（スペクトル／クロマトグラムのズーム、ピークのラベル付け、スペクトル／クロマトグラムの画像ファイルへのエクスポート、m/z値や保持時間値によるスペクトルの絞り込み機能など）を中心にパッケージを作成しました。このVer.4 Goldパッケージは4つのOS環境(Windows、MacOS、Linux Debian/Ubuntu、Linux RPM)でリリースされます。
