Did you first make sure that your McIDAS-X session was "pointing" (i.e. had a REDIRECTion) to the copy of SCHEMA that should exist in the directory in which nldn2md writes its output? If not, you may have just been checking to see whether or not the NLDN schema is registered in the copy of SCHEMA that comes with the McIDAS-X distribution. >.....but it was >already there and working fine at one time.

The SCHEMA MISMATCH error will only be seen when the decoder is attempting to write into an existing MD file. This may be the case if the SCHEMA has actually changed and one is in the middle of the day or if the MD file has not been scoured before it gets to be 10 days old. I am betting that the latter is the case. If it is the case that you have preexisting NLDN MD files, then you should make sure to scour them and then verify that the decoder can correctly file data. >thanks, Please let me know if your problem was one of a preexisting (i.e., old) MD file. Tom >From address@hidden Tue Jan 18 11:19:22 2000 re: Please let me know if your problem was one of a preexisting (i.e., old) MD file. Yes, I believe you are correct. When it started writing to a new MD file-day it worked fine. I think I originally had the thing pointing to the wrong or old SCHEMA file, and when I fixed that I forgot to remove the existing MD file. I do have another problem with with plotting the NLDN data, but I think it is unrelated to the SCHEMA problem so I'll send a separate email here in a minute. thanks for your help! Mike
