hi andrew,

thank's for the help.
when i use the command:
 > mincinfo  -attvalue time:step SC1CN022M1_42b_b45_5.mnc
i get the following message:
ncattinq: ncid 3: Attribute not found

here the normal mincinfo:
 > mincinfo SC1CN022M1_42b_b45_5.mnc
file: SC1CN022M1_42b_b45_5.mnc
image: signed__ short -32000 to 32000
image dimensions: time zspace yspace xspace
    dimension name         length         step        start
    --------------         ------         ----        -----
    time                       29      unknown      unknown
    zspace                     63       -2.425      -445.58
    yspace                    128      2.00331      -127.21
    xspace                    128      2.00331      -127.21

what i need is the following information getting from mincheader:
 > mincheader SC1CN022M1_42b_b45_5.mnc
netcdf SC1CN022M1_42b_b45_5 {
dimensions:
        time = 29 ;
        zspace = 63 ;
        yspace = 128 ;
        xspace = 128 ;
variables:
.........
.........
.........ecat-subhdr:Zfilter_Order = "0" ;

// global attributes:
                :history = "Fri Aug 26 15:50:06 2005>>> ecattominc 
-clobber -short
 -decay_correct 
/local/data/SC1CN022M/PET/SC1CN022M1/SC1CN022M1_42b_b45_5.v 
/tmp/itchy-19679/SC1CN022M1_42b_b45_5.mnc\n",
    "" ;
data:

 time = 0, 60, 120, 180, 240, 360, 480, 600, 900, 1200, 1500, 1800, 2100,
    2400, 2700, 3000, 3300, 3600, 3900, 4200, 4500, 4800, 5100, 5400, 5700,
    6000, 6300, 6600, 6900 ;

 time-width = 60, 60, 60, 60, 120, 120, 120, 300, 300, 300, 300, 300, 300,
    300, 300, 300, 300, 300, 300, 300, 300, 300, 300, 300, 300, 300, 300,
    300, 300 ;

in detail i need the "time" and "time-width" information.

oliver
