How to read pairs of data from a text file?

I have a few output text files arranged in one row, each pair of data is (x1,x2) i.e:

-0.00049249 0.000252263 0.000674042 0.000829539 0.000820268 -0.00049555 ...

how can I put it in two columns Xodd Xpar like this:

-0.00049249 0.000252263

0.000674042 0.000829539

0.000820268 -0.00049555

     .           .
I'm a new user, I'll appreciate any help. Ty in advance

A=[-0.00049249 0.000252263 0.000674042 0.000829539 0.000820268 -0.00049555]  
B=reshape(A,2,[])'

To read your text file you can use dlmread

A=dlmread('your_file.txt')
