Dear all,
 
I would like to know how can I compute the length of a string in a dataframe. Example:
 
SEQUENCE                               ID
TGCTCCCATCTCCACGG            HR04FS000000645
ACTGAACTCCCATCTCCAAT      HR00000595847847
 
I would like to know how to compute the length of each SEQUENCE.
 

Best regards,
João Fadista
