Hi Rob:
I have a file called _16.CEL. I want to find out the date information in
its header. The following gives me:
$ strings _16.CEL | grep DatHeader
DatHeader=[2..65534] _16:CLS=7365 RWS=7365 XIN=1 YIN=1 VE=30
2.0 10/27/06 10:57:45 50207590 M10
I find a date 10/27/06. Is this what you are looking for?
Best,
Saroj
