[visad] GMS-5 data

Dear VisAD users,
I am trying to read and navigate old Japanies GMS-5 data in McIDAS Aread 
format. However, I have problems with navigation of some images.
It reports an error that corrected navigation table was not present and 
navigation block is not filled well.
Have you someone worked with these data?
Thank you very much for any kind of help.
