2021-09-17 [Announcement] To my great regret, I have to stop the Development of REX.

  • これまで日本発のXAFS解析ソフトとして、REXを開発して参りました。また多くのユーザからご支持をいただき、誠に感謝しております。私自身これを世界標準にまで持って行きたく、これまで精力的な活動をしてまいりましたが、今後の開発推進にめどが立たなくなったこと。私自身もいつまで生きていけるかわからないことから．今後REXを普及する活動およびREXの新版の開発の活動を中止したいと思っております。もちろん、REXをお使いの方々からの質問は、私がまともに動ける間は受け付けますし、サポートも引き続きいたします。またREX自身はリガクさんから引き続き販売されると思います。また、必要なソフトの提供もできる限りいたしますので、ご安心いただきREXをお使いいただければと思います。ただ、XAFS教科書や講習解答では今後一切REXを扱わないことになると思いますので、もし必要でしたら、個人的におたずねください。リモート講義等は行っております。 なお、REXとは別に開発を進めてきましたMRMC法およびCTS法は引き続き開発していきたいと思いますので、何かございましたら，遠慮なく。 朝倉清高
