load 2nd column from a set of files into matrix

Share icon

Hi!
I have a large data set (.dat files) and would like to load only the second column from each file into a matrix. Any suggestions?
The loadwave function will allow you to load only the second column of data and that will be the first step, but since you mentioned data from multiple files I am assuming you would like all the column 2 data into a single matrix.

Do do that:
1. Load all the data from the column 2 of each file. You may need to write a small looping function to do the importing.
/L={nameLine, firstLine, numLines, firstColumn, numColumns } where /L={0,0,1,1} where the first 1 means start at column 2 (zero based counting) and the second 1, forces to only import 1 column.
2. Concatenate the now imported 1D waves using the promotion feature to create a matrix. The concatenate function can also delete the original 1D files for housekeeping purposes
Concatenate [ /DL /KILL /NP[=dim ] /O] [typeFlags ] waveListStr, destWave
