st: reshape question

[Nikolaos Pandis <npandis@yahoo.com>]

Hi to all
 
I would be grateful if you could possibly help me reshape to long the following wide data structure:
 
I have 28 patients (patient_id)
I have measured the distance between 6 pairs of anatomical points in those 28 patients on serial radiographs (5 radiographs per patient):
 
cda_c1 to cda_5
 
cggn_c1 to cggn_5
 
spame_c1 to spame_5
 
nspa_c1 to nspa_5
 
ara_c1 to ara_c5
 
argn_c1 to argn_c5
 
cda, cggn, spame, nspa, ara, argn indicate the linear measurement
 
c1 to c5 indicate the 5 time points.
 
I can reshape each variable (measurement) on its own:
 
for example: reshape long cda_c, i(patient_id) j(time)
 
but how could I reshape all at once in the same datafile?
 
Thank you,
 
Nick
