Yes .. I do it all the time.

My guess at your trouble is that you are manually extracting a 
table from the redirected standard output from a batch run.  
This is designed for screen viewing, and dates back to the 80's 
when viewing text on the screen was a common thing to do.

Probably the output of things like "1K" for 1000 are the 
problem.

I recommend instead that you direct the output of the individual 
commands to files, and view them.  When directed to a file, the 
output notation is in the usual "E" format that anything can 
read.  For example:

gnucap> tran 0 .001 .0001 >afile

Then view that file:

$ gwave afile

or from the gnucap prompt:

gnucap> !gwave afile


I am bewildered that it works different in gnuplot.  I thought 
the same formatting issues would apply there too.

Also ..

When doing a transient analysis, you will get a better plot if 
you say "trace all" ..  example:

gnucap> tran 0 .001 .0001 trace all >afile
gnucap> !gwave afile
