Hi Samir,
Ferret is not able to see definition of minutes from your script which is the root cause of all errors.
if you type yes? list minutes are you able to see the numbers?

Dear Ferret users,

I am trying to convert abstract data (which is in x axis) in time axis using days1900 using ferret v6.303 (AIX version)

I have got 31185 steps. I have gone through the FAQ and adopted the following procedure

!------------------------------------------------------------
LET day_frac = (hour + minute/60 ) / 24
LET tstep = DAYS1900(year,month,day) + day_frac

DEFINE axis/T/T0=1-jan-1900/UNIT=days ttaxis=tstep[L=1:31185]

LET dummy=t[GT=ttaxis]
LET p = RESHAPE(p1,dummy)
!--------------------------------------------------------------

However it is giving following error

**ERROR: variable unknown or not in data set: MINUTE
**ERROR: unknown defining grid: GT=TTAXIS

I tried to do it in several ways but the error remains the same.

Hope to get help from users who have solve this type of issue earlier.

Thanking you in advance.

Samir
