I noticed that you were looking through the FRNTDISP McIDAS web pages yesterday. I was curious to know what was going on, and now I know. >If I use the DEFUALT .NAM file (ie real time data) I can get fronts to >plot on a GOES image with no problem using a simple command like >FRNTDISP OLAY LATEST FRNTDISP typically does not use the ASUS1* or FSUS2* files. It goes through ADDE to the machine for which you have a RTWXTEXT DATALOC. The reason I say typically is FRNTDISP can be run off of a text file by using the FILE= keyword. >But I want to make my own ASUS files for historical events and overlay >those fronts onto sat. images from the same time period. OK, this should be no problem. >So I set my redirection like this: > >ASUS1* /home/ocooper/MAY99_STE/Mcidas > >And I copied the ASUS file that worked with the real time data to this >directory. OK again. >Then when I issue the command >FRNTDISP OLAY LATEST >i get the following message: >FRNTDISP: Front not available for Try the following invocation: FRNTDISP OLAY LATEST FILE=file_name Here, 'file_name' is the name of the file in your /home/ocoopr/MAY99_STE/Mcidas directory (it is NOT the fully qualified pathname). For this to work, you _do_ have to have a valid REDIRECTion for the file(s). >Why does changing the redirection cause the FRNTDISP command to fail? It should have nothing to do with FRNTDISP unless you are using the FILE= option. If it actually is having something to do with the operation of FRNTDISP, then there is a bug in the code. I have to tell you that I was working on FRNTDISP at the end of last week (mod for an upcoming format change to the ASUS1 and FSUS2 bulletins). I had occasion to run the routine numerous times in the standard, ADDE mode and from data in text files using the FILE= option. I did not see that changing the REDIRECT for ASUS1* files changed the operation of the routine when going to an ADDE server. A couple of things to check on: o what is your DATALOC for RTWXTEXT: DATALOC LIST RTWXTEXT o was the time of the image you were trying to overlay on around 0Z Tom
