[ferret_users] error using MC files

[Elodie Martinez <elodie.martinez@xxxxxx>]

Dear Ferreters,
I have data that spans multiple files. I have used many times mc files without any probles till now.
The data are every 8days so the s_delta =8.
 However, my mc file only works when  I enter s_delta=1. (which is wrong of course because it  should be 8 days)
when s_delta is something else than 1, I have the following message error:

At line 228 of file mc_init_dset.F
Fortran runtime error: End of file

My simplified code to read only 1 file at the moment is below:

 &FORMAT_RECORD
     D_TYPE        = '  MC',
     D_FORMAT      = '  1A',
     D_SOURCE_CLASS       = 'multi satellite OUTPUT',
 /
 &BACKGROUND_RECORD
      D_EXPNUM      = '0001',
      D_TITLE       = 'Globcolour Chl',
      D_T0TIME      = '1-Jan-1970 12:00:00',
      D_TIME_UNIT   = 86400.0,
      D_TIME_MODULO = .FALSE.,
 /
 &MESSAGE_RECORD
      D_MESSAGE     = ' ',
      D_ALERT_ON_OPEN      = F,
      D_ALERT_ON_OUTPUT    = F,
 /
 &EXTRA_RECORD
 /
 &STEPFILE_RECORD
       s_filename    = 'PolF-1997-1998_Glob_Wei_4km-8d.nc',
       S_START       = 10110,
       S_END  = 10587,
       S_DELTA       = 8.0,
       S_NUM_OF_FILES       = 1,
       S_REGVARFLAG  = ' ',
 /
 &STEPFILE_RECORD
       s_filename    = '**END OF STEPFILES**'
 /






When I simply load my initial file I have the following informations :

./PolF-1997-1998_Glob_Wei_4km-8d.nc  (default)
 
 name     title                             I         J         K         L         M         N
 CHL                                       1:720     1:840     ...       1:61      ...       ...
             units on grid GAM1 with -999 for missing data
             X=160W(-160):130W(-130)  Y=30S:5N 
 
  time range: 06-SEP-1997 00:00 to 27-DEC-1998 00:00

and if I list t[gt=chl]:

             VARIABLE : T
                        axis TIME2
             FILENAME : PolF-1997-1998_Glob_Wei_4km-8d.nc
             SUBSET   : 61 points (TIME)
 06-SEP-1997 00 /  1:  10110.
 14-SEP-1997 00 /  2:  10118.
 22-SEP-1997 00 /  3:  10126.
.......
  11-DEC-1998 00 / 59:  10571.
 19-DEC-1998 00 / 60:  10579.
 27-DEC-1998 00 / 61:  10587.

I am wondering if it could come my time axis which has values about 10000. (some other files I read with mc files too, and also starting in september 1997, have time values around 730000 )

Has any one already encounter this problem?
thanks a lot for your help!!!!
Elodie
