I have a data file with 7 columns and 100 rows. How do I import data from
that into 7 different arrays in Mathematica ? The data is in exponential
form and is tab separated. Top few rows are shown at the end of this

The cut and paste has junked up the things a bit. But there are 7 columns
and 100 or so rows.

Second question : how do I do a linear fit of of one column as x and
another as y ?

What is the format of such an output ?

I will really be thankful if you could send a CC to me at my email
