Issue with fancplot

[TomSexton00]

Hi, I've been a satisfied user of FAN-C for a number of years, but after a recent wave of server updates (we are now on FANC/0.9.27), there is now a bug with running a fancplot command which previously worked:

fancplot [REGION] -p triangular -vmax 0.05 [HIC OBJECT]

Now returns this error message:

/shared/software/miniconda3-admin/envs/fanc-0.9.27/bin/fancplot:187: UserWarning: There was an error with plot 0, region chr10:15000000-16000000 (Traceback (most recent call last):

Many thanks for your advice.

Hi Tom,

sorry about the delay - the time leading up to the holidays is always particularly busy.

The error is due to recent updates in Matplotlib. However, FAN-C 0.9.27 should have fixed the issue. Can you run

fancplot -V

to double-check that the correct version is installed? Sometimes the executable points to an older version despite being installed in a different environment.

I also downloaded the 0.9.27 source files directly from Pypi and the line that raises the error in your case (669 in base_plotter.py) is different. It should read

self.cax.figure.draw_without_rendering()

I hope you can figure out where the version mismatch comes from!

Best,

Kai

Hi Kai, Thanks. Indeed, the fancplot running is 0.9.25. I will see with IT about getting the proper update, and hopefully that will fix things. Happy Christmas to you and everyone else from the Vaquerizas lab, past and present, who see this! Tom

Hi, i'm having a similar problem, but i've recently installed fanc for the first time, so is likely that the problem is me. My version of fancplot is the latest, like matplotlib, there is the error:

File "/home/omen/PycharmProjects/FancExt/main.py", line 30, in <module>
    p.plot('chr3')

I would like to take this opportunity to wish you a merry Christmas and kindly thank you for your support
