Hi Kun, I apologize for the slow replies. I am currently in Burkina Faso attending a conference. The network connections here are not good, so my ability to respond to inquiries is limited. > I use McIDAS to extract met5_band8 data intially named as > mcidas_Meteosat-MVIRI-MTP15-NA-NA-19990612180000.000000000Z > and obtained from EUMETSAT Archive.

AXFORM works on images in McIDAS AREA file format. The METEOSAT images from the EUMETSAT archive are most likely not in AREA format, so AXFORM will not work on them. > You > know, I am sure I did every step correctly and used the below command line, > but all value of the extracted .A01 are zeros.

Thank you very much. The image is not in AREA file format, so AXFORM will not work. Instead, you will need to setup an ADDE dataset and serve the data out of the file you downloaded from EUMETSAT. Please review the online help and Users Guide section on creating ADDE datasets using DSSERVE. It would also be a very good idea to work through the McIDAS training workshop materials so you better understand ADDE and how to create an ADDE dataset: http://www.unidata.ucar.edu/software/mcidas/2006/workshop/toc.html Again, I apologize for the slow responses, but the network conditions here in Burkina Faso are not good, so my ability to communicate is limited. Also, I am the only person in Unidata that answers McIDAS support questions, so resending your inquiry will not help. You could, however, subscribe to the Unidata McIDAS-X email list and post your inquiries to it. You can (un)subscribe to any Unidata-maintained email list online at: http://www.unidata.ucar.edu/content/support/mailinglist/mailing-list-form.html Please wait until AFTER you have received notice of being subscribed before posting to the list. If you don't, your email will simply bounce back to Unidata User Support. Also, if you decide to subscribe and post to the list (and you must be subscribed in order to post), please let people know that you got your data from a EUMETSAT archive. This will be important information for them to know.
