DeconvolutionPreview plus STF

[Alejandro Tombolini]

Hi Juan, when after using DeconvolutionPreview scritp (Default values) in this image, PI crashes when you apply STF on the DeconvolutionPreview image.
Tested in the full image and small previews

PixInsight Core 01.08.06.1474 Ripley (x64) on Linux

Saludos, Alejandro.

Hola Alejandro,

I can't reproduce this on previews (and cannot invest the time necessary to check this on the entire frame right now). Can you tell me the coordinates of a preview where this happens (small, if possible)?

[Alejandro Tombolini]

Hola Juan, it is strange, it happens in any preview on my PC. I am using STF with linked channels

Attached an image with the preview coordinates of a new test.

Hope this helps

Saludos, Alejandro.

[Juan Conejero]

Strange indeed. I can apply the DeconvolutionPreview script to this preview and then apply STF to the 'DeconvolutionPreview' image without problems, linked or unlinked.

What distro are you running on?

[Alejandro Tombolini]

mmmh, may be a PC problem, but I'm "not having" knows problems... I will investigate.

Thanks!!!

Saludos, Alejandro.

I am on Red Hat EL 7.6. Ubuntu 16 is old but well supported. I don't know why this happens...

Do you get a crash report generated by PixInsight (a stack trace) and can continue, or does the application exit in an uncontrolled way?

[Alejandro Tombolini]

Yes!!, I have to update it  .

No messages, the application exits. See this viedo

Saludos,
Alejandro.

Hi Juan,

I updated to Ubuntu 18.04

No changes. Attached is a screenshot of the system after PixInsight close. I don't know if says something useful.

I will continue investigating this

Saludos, Alejandro.

This looks like a conflict between system libraries and libraries included in the PixInsight distribution for Linux. Can you try removing (or better, renaming) the libstdc++ libraries on the bin/lib directory?

[Alejandro Tombolini]

Hi Juan, I renamed the file and the same, but I discovered something new. If apply STF without 24 bit lookup tables it works fine, and PI closes only when I select it again 24 bit.
Ram Memory problem?

Saludos, Alejandro.

Hi,

Tuve el mismo problema con W10.
Este bloqueo no ocurre en DeconvolutionPreview sino en STF.

Mi imagen era un "maestro" de luminancia de 130 MB, rico en estrellas – NGC 7635 Nebulosa de la Burbuja.

-   Con una pequeña vista previa, DeconvolutionPreview funciona correctamente y genera un archivo (después de guardarlo) de 60 MB después de aproximadamente 1 minuto. Después de cerrar DeconvolutionPreview y recargar el archivo de 60 MB, STF funciona correctamente.

-   Con la imagen completa, DeconvolutionPreview tarda media hora, y la imagen guardada "pesa" 3,2 GB 
Después de cerrar DeconvolutionPreview, y la recarga normal de esta enorme imagen, con Ctrl+A, STF consume toda la memoria RAM del PC (8GO) y "congela" el ordenador.

La imagen completa no parece necesaria, pero aún así, STF no sabe cómo manejar estas situaciones extremas.
