Good afternoon I have found a really useful software package for chemistry modeling but I need to install and run Cygwin to use it. I don't understand how to run Cygwin. Presently, I am running Windows XP on my system. I understand the premise behind Cygwin as stated on the website. However, I find the list of compilation instructions confusing. I appreciate the level of detail with which you keep your website and detail with which the Cygwin program must run. I am interested in focusing my time on running Ghemical. I am less interested in knowing everything about Linux based systems. That I leave to the experts. Could you please tell me how to install Cygwin properly? I understand that I need Gnome. Could you also provide a hint at how I am to compile Ghemical? I would greatly appreciate any assistance you could provide. http://bioinformatics.org/ghemical/download.html Thanks
