Eigen Value recorder problem

[farshid2010]

Hi every one!

I can get the eigen values of model easily by the following command:
puts "eigen values at start of transient: [eigen $NStory]"
It yields the Nstory eigen values.
the problem is the values show great difference with the values obtained by the recorder command:
recorder Node -file Mode.out -time -node (all node written manually example: 11 12 ...) -dof 1 "eigen $NStory"
what is the problem?
while the results obtained by the eigen command are quiet logical!


another question:
when using :

set Range ""
for {set level 1} {$level <=[expr $NStory+1]} {incr level 1} {
for {set pier 1} {$pier <= [expr $NBay+1]} {incr pier 1} {
set nodeID [expr $level*10+$pier]
lappend Range $nodeID
}
}

eval "recorder Node -file Mode.out -time -node Range -dof 1 "eigen $Nstory""

I get this error:
extra characters after close-quote
while executing
eval ""recorder Node -file Mode.out -time -node Range -dof 1 "eigen $Nstory""


What is the reason?
Thanks in advance for the help!

they are 2 different things .. one is the eigen values the other is the eigen vector components for the particular eigenvalue stored at the nodes!
