Hi, re: > Ok let me try that tomorrow morning and report back to you. OK. re: > Dont know what you mean by: " I meant attach one of the actual image files > to your reply. I would like to get the actual disk file in which the image you are trying to display exists. I am not sure if this would be a file name like: 2011117161500_effrad.area or like: 2011117161500_effrad.c01 I suspect that the images are in the files with the '.area' suffix, but I can not be 100% positive. I could be certain after seeing how the G13 dataset is defined in your McIDAS-X invocation. You give me the information by sending the output of: DSSERVE LIST G13 re: it would be a lot quicker for me if you cut and pasted output text into your email reply instead of doing screen captures (both work; inline text is faster for me)." > Can you show me an example of what you want here? Sure. Here, for instance is the output from IMGLIST for a dataset whose group name is TOPO that I have defined in my McIDAS session: IMGLIST TOPO/CONF FORM=ALL Image file directory listing for:TOPO/CONF Pos Satellite/ Date Time Center Res (km) Image_Size sensor Lat Lon Lat Lon --- ------------- ------------ -------- ---- ---- ----- ----- ------------ 1 TOPOGRAPHY 1 JAN 96001 00:00:00 45 105 Band: 1 No Information Available 8.09 8.09 1000 x 1500 proj: 0 created: 1996001 0 memo: --- 1-BYTE TOPOGRAPHY FILE --- type:PRD cal type:BRIT offsets: data= 3328 navigation= 256 calibration= 2816 auxiliary= 0 doc length: 0 cal length: 0 lev length: 0 PREFIX= 0 valcod: 0 zcor: 1 avg-smp: A lcor: 2899 ecor: 4000 bytes per pixel: 1 ss: 11 Resolution Factors (base=1): Line= 8.0 Element= 8.0 IMGLIST: done The dataset that you have been trying to display using IMGDISP has the group name GIS and descriptor VIS27APR11. The general form of an McIDAS ADDE dataset is: group/descriptor.pos Here: group - group name of a dataset descriptor - descriptor name for a dataset pos - position in the dataset To get an idea of what all 'pos'itions (elements) in an ADDE dataset look like, run: IMGLIST G13/VIS27APR11.ALL This is the default short listing. A full listing would be: IMGLIST G13/VIS27APR11.ALL FORM=ALL You can find out more about McIDAS commands either through the built-in help, or through the McIDAS User's Guide. For instance, the built-in help for IMGDISP can be seen with: HELP IMGDISP To see all of the commands available in McIDAS, you would leave out the name of the command you want help on: HELP NB: there are LOTS of commands in McIDAS, so the listing from HELP will be long The Unidata McIDAS-X User's Guide is found in: Unidata HomePage http://www.unidata.ucar.edu Software http://www.unidata.ucar.edu/software McIDAS http://www.unidata.ucar.edu/software/mcidas Documentation and Training https://www.unidata.ucar.edu/software/mcidas/#documentation The McIDAS user's guide https://www.unidata.ucar.edu/software/mcidas/current/users_guide/toc.html I tend to skip down to: Chapter 3 - Commands https://www.unidata.ucar.edu/software/mcidas/current/users_guide/Commands.html#40196 Commands by Alphabetical Order https://www.unidata.ucar.edu/software/mcidas/current/users_guide/CommandsbyAlphabeticalOrder.html#26670 re: > Thanks for the efficient response.
