You must also copy ROUTE.SYS and SYSKEY.TAB to that same directory. The read/write permissions on all three files should be 664 _assuming_ that your 'ldm' and 'mcidas' users are in the same group. >I tried doing some searches on this type of error and I didn't see anything >out there. Any ideas? Thanks in advance, If you are doing an initial setup, then I suggest: o stop the ldm: <login as 'ldm'> ldmadmin stop <wait for all LDM processes to exit> o <as 'mcidas'> NOTE: if you already have the files ROUTE.SYS and SYSKEY.TAB in the directory where you want NLDN data decoded, do copy new versions to that directory! cd ~mcidas/data cp SCHEMA SYSKEY.TAB directory_where_you_want_NLDN_data_decoded cd ~mcidas/workdata cp ROUTE.SYS directory_where_you_want_NLDN_data_decoded o make sure that McIDAS has file REDIRECTions that will access NLDN MDXX files in the directory where you want NLDN data decoded. To test to see if you already have a REDIRECTion, run the REDIRECT LIST command and look for a pattern that will match MDXX files 71-80. These will look like: MDXX007* directory_where_you_want_NLDN_data_decoded MDXX0080 directory_where_you_want_NLDN_data_decoded If you do not have the necessary REDIRECTions, add them: <still as 'mcidas'> cd ~mcidas/workdata redirect.k ADD MDXX007\* \"directory_where_you_want_NLDN_data_decoded redirect.k ADD MDXX0080* \"directory_where_you_want_NLDN_data_decoded o remove any NLDN MDXX files that may have been created by your earlier attempts to get the NLDN data decoding working: <as 'ldm'> cd directory_where_you_want_NLDN_data_decoded rm MDXX007* MDXX0080 This last step is important because the error message you report above shows that you do have a file of the appropriate name, and it is bad. o after all of the above has been done, restart the LDM: <as 'ldm'> ldmadmin start Tom
