"SPECMAN" is an binary format for several spectrophotometers of JASCO; (http://www.jasco.co.jp/) I tested only UV-VIS spectrophotometer (model UV560). However, it may work with other apparatus. Hello All, I updated one of my XOP, LoadSPECMAN2. If you are an user of IgorPro and JASCO's spectrophotometers, it may help you to work together. Files are LoadSPECMAN2_mac.zip for Mac OS X LoadSPECMAN2_win.zip for Windows Please test one of them. This XOP was made many years ago. Recently, JASCO allowed me open it to the public. If you wish to obtain other versions of this XOP, please contact me. Mamoru Yamanishi , April 2011
