How to combine the output of alphaMELTS to get tables and plots

[hyjwhyjw]

Using EASYMELTS, I had access to MELTS.OUT and many TBL files, and later via

https://magmasource.caltech.edu/gitlist/Combine_tbl.git/blob/master/MELTS_Excel-Combine_tbl_2.zip

, the results were easily combined to automatically create tables and charts similar to the MELTS for Excel

However,

I followed the alphaMELTS (double-click) version of the tutorial

https://magmasource.caltech.edu/forum/index.php/topic,752.msg974.html#msg974

At the end of the program run, I don't see MELTS.OUT in the specified OUTPUT folder, and the output filenames are all. txt:

alphaMELTS_tbl.txt

Bulk_comp_tbl.txt

Liquid_comp_tbl.txt

logfile.txt

Phase_main_tbl.txt

Phase_main_tbl.txt

......

What should I do to combine the output of alphaMELTS and get tables and plots similar to MELTS for Excel?

Hi,

alphaMELTS 1.9 (double-click) doesn't have a way to generate the melts.out and .tbl files. You just have to import the .txt files into Excel individually (though you don't need logfile.txt or alphaMELTS_tbl.txt if you do the others). Using column_pick.command to generate a single file with the values you are interested in is an option. That way you only have to import one or two .txt files instead of 5.

Alternatively, alphaMELTS 2 has an option to output GUI-style files like the easyMelts ones, as described in its tutorial:

https://magmasource.caltech.edu/forum/index.php/topic,975.0.html

It also has a more flexible column-pick.command script, which not only allows you to pick columns from existing files but also to automate calculation of variables. E.g. see this workshop example:

https://magmasource.caltech.edu/gitlist/Workshops.git/tree/main/workshop_files/RC12frac_b_withcolcustom/alphaMELTS2/

You can use the value from an earlier column by putting curly brackets around the name, like in the example which calculates FeO^tot, Mg#, and Mg# as %:

! custom expressions need to be at the end and are processed left to right; avoid special characters like in FeO* or Mg#
File: Liquid_comp_tbl.txt
Table: "Liquid Composition"
Columns: SiO2 TiO2 Al2O3 Fe2O3 Cr2O3 FeO MnO MgO NiO CaO Na2O K2O P2O5 H2O CO2 FeOtot={FeO}+0.9*{Fe2O3} Mgnum=({MgO}/40.3044)/(({MgO}/40.3044)+({FeO}/71.8464)) Mgpc=100*{Mgnum}

Thank you Paula!
But where can I download the alphaMELTS 2 ?

[Paula]

Click the alphaMELTS 2 link in the reply (https://github.com/magmasource/alphaMELTS). It'll take you to the alphaMELTS source repository. Soon the releases will be hosted there, but in the short term, there are separate links to download pages for alphaMELTS 2 and alphaMELTS for MATLAB/Python.
