Re: need help reading ascii

Dear Ipsita,

The last argument to readAsciiTable should be: (/number of header lines to skip, number of footer lines to skip/)

>From the file below, it looks like you have 4 header lines, and possibly no footer lines, so use (/4,0/) or just 4 for that argument, instead of (/2,2/).

In some cases, you don't even need to indicate how many footer lines you have, if they don't have any numbers in them. This function won't try to read anything that doesn't contain numbers.
