How to interpret the Phase_main_tbl.txt

[mazhiwangxy]

I am using alphaMELT (ver.1.2.0) based on windows. The output text confused me. For the Phase_main_tbl.txt, what does the first four columns means. For example, at liquidus temperature, in the liquid phase the four columns are 99.518, -1275,  270.347 and 41.55. But for the plagiocalse phase, the four columns are 1.055, -14664. 2.398, 1.279. It seams that 99.518 and 1.055 are mass. But what are the remain three columns mean?
And I also want to ask how to calculate the volume of each phase.

It sounds like you are running the alphamelts_win64.exe directly rather than the run-alphamelts.command Perl script. Did you install Perl and run the install.command script? If so, then try working through the tutorial to see how to call alphaMELTS:

Make sure you exit the program before trying to open the output files. This allows the run-alphamelts.command  script to process the Phase_main_tbl.txt file so that it is more understandable.

If you didn't install alphaMELTS, or if you can't get it to work as described in the tutorial example... then please be patient. There is a much easier way to install Perl and alphaMELTS on Windows coming soon that would be worth waiting for - it's not quite ready yet but should be sometime in the next month or so.

In the meantime, you can run the alphamelts_win64.exe file but you should choose the old graphical user interface style of output (which is the same as easyMelts generates). You can do this by adding a line "Output: both" or "Output: tbl" in your .melts file.
