Dear Sir/Madam, I have installed ccplot in Ubuntu 18.04 LTS app on my PC (Windows 10). For the installation process, I followed the user guide which is available on the website (https://ccplot.org/download/). The steps I followed for the installation process is given below: 1. To install the required libraries and ccplot: sudo apt install --no-install-recommends python3 python3-dev gcc python3-distutils cython3 libhdf4-dev libhdfeos-dev python3-pil python3-numpy python3-matplotlib python3-mpltoolkits.basemap ttf-bitstream-vera 2.Build and install ccplot: tar xzf ccplot-1.5.6.tar.gz cd ccplot-1.5.6 sudo python3 setup.py install After that to check the version I simply run the 'ccplot -V' command to print the version of the ccplot and the output came is in the following: ccplot 1.5.6 Third-party libraries: matplotlib 2.1.1 basemap 1.1.0 Copyright (c) 2009-2015 Peter Kuma. This software is provided under the terms of a 2-clause BSD licence. Now after that I wanted to make a plot from a hdf file of CALIPSO data using ccplot as per the instruction given in the Chapter 6 of 'Visualising Data from CloudSat and CALIPSO Satellites'. I have made a directory named 'HDF' inside the folder 'ccplot-1.5.6.' where I put the hdf files I want to plot. 1. First I gave the command to know the information about the file ccplot -i HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf and the output came Type: CALIPSO Subtype: profile Time: 2006-06-13 07:44:32, 2006-06-13 07:47:00 Height: -1815m, 39855m nray: 200 nbin: 583 Longitude: 84.06E, 86.27E Latitude: 21.55N, 30.46N So up to this step, I think this is working fine. But when I wanted to plot and gave the command below it throws an error! ccplot -o calipso1.png cmap/calipso-backscatter.cmap calipso532-layer /HDF/CAL_LID_L2_05kmCLay-Standard-V4-20.2006-06-13T07-20-12ZD_Subset.hdf ccplot: calipso532-layer: HDF: SDstart failed: b'Bad file name on open'. Does it mean ccplot is not installed properly? Can anyone tell me why this is happening? And how to solve this problem? I am very new to this software tool and any help on this is very much appreciable. For your convenience, I am attaching the sample file and also the lines that came during the installation of the ccplot to check if the ccplot is installed properly or not. Please find the attachment. Thank you. Sincerely, Ankan Sarkar DST-INSPIRE Fellow National Institute of Technology Rourkela |
