Ouch. >the image I'd like you to work on is only the NCAL type, given that IR, WV >and 4km VIS work fine. OK. >add some more under http://metsun1.met.sjsu.edu/~leoncini/images I downloaded the Nov. 2 NCAL images from the URL above to a Linux machine at home and verified that IMGDISP does not work. I was, however, able to load and draw a map on top of the images using the old DF routine. In order for DF to work, one has to make a link between the image file (e.g., NCAL_010712_1930) and an AREA file name (e.g., AREA2005). Here is an example: ln -s NCAL_010712_1930 AREA2005 After making the link, you have to tell McIDAS how to locate the AREA file with a file REDIRECTion. Here is an example of the procedure for an NCAL file in a directory named /data/mcidas/sjsu: cd /data/mcidas/sjsu ln -s NCAL_010712_1930 AREA2005 Now, in your McIDAS session, you would type: REDIRECT ADD AREA200* "/data/mcidas/sjsu and then verify thst you had no typos: DMAP AREA200 you should get a listing that shows the existence of AREA2005 in /data/mcidas/sjsu. Next, verify that you can load the image using DF and draw a map on it using MAP: DF 2005 1 AU 1 1 EU=IMAGE MAP H Since DF works, it would seem that there MUST be a problem or an assumption with/in the image server (AGETSERV) that IMGDISP runs to get data. I will investigate this further today and see if I can come up with a fix or workaround. After loading the image, it can be interrogated using the normal McIDAS D and IMGPROBE commands. Is this one of the things you are wanting to do? Just for completeness, can you verify that you are running Version 7.7x of Unidata McIDAS? This can be done by typing the folloeing from the Text and Command window of your McIDAS session: SEE VERSION.TXT Please let me know the output from this invocation. Thanks. >thanks again!! Sorry for the problems... Tom
