data table for larch data group
Matt,
If I read an ascii file with read_ascii() like so:
a = read_ascii(file)
The "a" group has a data attribute which contains the entire data table
as a 2D array. It also has 1D arrays for each column from the data
table. Those 1D arrays have attribute names taken from the column labels.
If I do something to change the data table, is there a function that I
can call that repopulates the 1D arrays with the columns of the altered
data table?
For example:
a = read_ascii(file)
a.data is, say, array
Hi Bruce,
At the moment, No. But that should be easy and a very good idea to
separate reading headers plus the data table from naming of the 1d
arrays... Like, I often run into cases where I want to rename arrays after
reading the file. I'll work on that.
I'd also like to be able to sensibly handle columns of non numeric data.
Maybe that's too separate a topic....

For example:
a = read_ascii(file)
a.data is, say, array
a.data = a.data[:, (0 .. 10)]
now a.data is, say, array
a.repopulate_arrays() # <---- the thing i am looking for....
Now a.energy, a.i0, etc should be array
Hope that's clear.

Not this topic but a very good idea nonetheless.
