sum group conc

Contents: Description, Arguments, Usage, Examples, Related Functions, Source Supported Under Version: > 1.03 Current .dvrc Version: 1.24 Description Sum concentrations from sma output according to group labels. Calculate statistical errors associated with each group abundance. The group=1 option in sma calls this function. Arguments and Return Values arg1 = .endlib from sma output (must contain .group arg2 = .conc from sma output arg3 = .measured from sma output arg4 = .nsamples from sma output arg5 = .bb from sma output arg6 = (optional) .forcedlib from sma output (must contain .group) Returns mineral group concentration maps with labels: .grouped_conc, .grouped_labels Also returns propagated group errors Groups are formed by scanning .group, and forming a new group index every time it encounters a unique group label. So, 'sheet-silicate' and 'sheet silicate' would be different groups. If you want to combine groups, like 'clays' and 'glass', you have to change both labels so that they match (such as 'clays + glass') and re-run sum_group_conc. Usage Syntax: sum_group_conc(arg1,arg2,arg3,arg4,arg5,[arg6]) Errors/Messages: “Number of group labels must equal z-direction of .conc. Perhaps you have an atmospheric library to add?” --.conc includes concentrations from your mineral library and your atmospheric library. You must include both libraries as arguments.
