I am new to Mathematica, and I find that there may be a lot of ways of doing this. I was wondering which one might be the most general.
I am importing data from .txt
files, resulting in a ragged array due to many lines containing parameters and other comments which I want to ignore.
I just want to import the numbers, and ignore the comments.
I am using this:
Import["filename.txt", "TSV", "HeaderLines" -> 15]
I have no TrailerLines that I need to skip, however, there are many rows halfway through the data which I would like to remove. These lines all start with #
, which makes me think that there is a way to just specify that any line starting with #
be skipped.
Thanks a lot in advance to anyone who might be able to help me with this.
DefineImportStreamMethod
to do this, but it's use becomes more complex: you have to open the stream first with the method, and then useImport
. But,Import
's ability to use streams is undocumented, so your mileage may vary. $\endgroup$ – rcollyer Aug 20 '13 at 14:38
