Hi Xuance,
The problem with reading in melts files is probably a path problem (see
here).
By 'update' I am guessing that you mean update the
melts_file. To do that use option 14. You will be given the option to write out the liquid composition or the residue composition (or in certain circumstances the bulk composition) in
melts_file format. There is more information about this option in the manual.
To create a new input file I usually just copy an old one and edit in a text editor, such as Notepad if you are on Windows. To make more that one
melts_file try the '-t
table_file' switch for run_adiabat.pl. Again there's more about this in the manual.
If anything doesn't work please don't hesitate to post again (I've been on leave but I'll be around more from now on so your post will get answered...).
Cheers,
Paula
