Kubuntu 15.04 x86_64. When trying to start the application it fails with this error:

"No handlers could be found for logger "lxnstack-root-logger"
QWidget: Must construct a QApplication before a QPaintDevice
Aborted (core dumped)"

On attempting to launch lxnstack I get the following error:

Traceback (most recent call last): File "/usr/bin/lxnstack", line 115, in <module> mainApp = main_app.theApp(lang,args) File "/usr/share/lxnstack/main_app.py", line 505, in __init__ self.setDisplayLevelsFitMode(0) File "/usr/share/lxnstack/main_app.py", line 1188, in setDisplayLevelsFitMode self.generateScaleMaps() File "/usr/share/lxnstack/main_app.py", line 2885, in generateScaleMaps qimg = utils.arrayToQImage(data2,bw_jet=self.use_colormap_jet,fit_levels=self.fit_levels,levels_range=self.levels_range) File "/usr/share/lxnstack/utils.py", line 1338, in arrayToQImage if img ==None: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Edit:
Changing lines 1338 and 1242 in /usr/share/lxnstack/utils.py to if img.any()==None: and if data.any()==None: respectively allows the program to launch, not sure if this causes any other issues yet.

Hello! Just trying out the current version of lxnstack from Github, and after installing it (and all dependencies) I get an error:

Have I done something wrong?

Kubuntu 15.04 x86_64, lxnstack installed from here: http://sourceforge.net/projects/lxnstack/files/binary%20packages/lxnstack-1.4.4.deb/download
Application successfully starts but starts consuming 100% on one of the CPU cores. Also, if the app is in the focus X process consumes around 25-35% from another CPU core.

Add a scheduler/timer capable to manage and plan the video capturing.

When trying to decode a CR2 file generated by a Canon EOS 400D, the following exception is raised:

I am getting a few Python related problems when I launch lxnstack 1.4.4. Specifically problems along these lines:

$ lxnstack
FITS support enabled
CR2 support enabled
Traceback (most recent call last):
  File "/usr/bin/lxnstack", line 115, in <module>

    if img==None:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

This happens immediately when I launch lxnstack as shown. I believe I have all the right dependencies installed:

$ python --version
Python 2.7.12

$ lsb_release --all
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial

Add support for creation of lightcurves of moving objects (like asteroids, etc.)

Create algorithms for wavelets correction and convolution/deconvolution.

Add an header editor capable to manage the FITS cards when saving the image.

Sometimes the program hangs while searching for hot pixels.
The following backtrace can be obtained by stopping the program manually with Ctrl-c in the console:

RGB Fits files saved with lxnstack cannot be opened by other programs like Sao DS9.

Currently FITS datacube can be only read and with some limitations.
Lxnstack should be able to read and write FITS datacube and the user should be able to choose the format of the output data (single HDU with multidimentional data or mupliple HDUs with 2D/1D data)

The new versions of pyfits use a different syntax from the version in Ubuntu 12.04. This leads to errors when reading/saving FITS file.
