Detection in progress

[mariasimone308]

Hi! As a beginner with this package I've chosen to use the shiny-based application with the command MtreeRing::ring_app_launch().

First I uploaded the image, and cropped it without problems, but after creating path correctly, when I click on the "Ring Detection" then the application gets stuck in "Detection in progress" for hours, without final results, even if the file is in the right format (jpg) and the size is <10MB.
Also I've kept the default setting for the Labels and Detection windows. I tried with different format, or different files, but is always the same.
Thanks for the help.

Thank you for your interest in this package.
This problem may be caused by the update of other R libraries that MtreeRing relies on. After clicking on the "Ring Detection" button, could you please provide some messages shown in the console of RStudio? Like this:

If your RStudio console showed the same problem as above, you can try to choose 'measuRing' as the detection method. This option is on the right side of the app window.

After clicking "Ring Detection", this message appears in the console:

MtreeRing::ring_app_launch()

I tried the measuRing detection and it works, but how can I use the others detection methods, since I can't use the "Inclined tree rings" with measuRing?

This error is caused by the update of an image processing R package. I will locate and fix this bug as soon as possible. Thank you for your feedback.

Before a new version of the app is available, an alternative solution is to use the ring_detect function, like the R codes below:
img.path <- system.file("001.png", package = "MtreeRing")
t1 <- ring_read(img = img.path, dpi = 1200, plot = FALSE)
t2 <- ring_detect(t1, seg = 3, incline = T, method = 'watershed', border.color = 'green')

Are there any progress with this issue?
