A question about node recorder command

[foadEng]

Hi
What is the difference between these two recorders :

recorder Node -file def_mode_1.out -node 9902 9903 -dof 1 2 3 eigen 1
&
recorder Node -file def_mode_1.out -node 9902 9903 -dof 1 2 3 "eigen 1"

I want to calculate modal shapes but these two recorders give different results so I don't know which one is correct!
I would really appreciate any help.
Thank you

the first will give you the results for all eigenvalues (1 line per eigenvector) for all modes .. the second will give you the eigenvector for the first mode .. to see for yourself, do a print node nodeTag? and comapre eigenvectors in file with those printed on screen.
