DCC throws value error?

[mathavanpu]

hi, I have executed the DCC, the circular RNA counts and co-ordinates files are generated. For finding the CircSkipJunction I got the error mentioned below. Can you please guide me resolve this

Traceback (most recent call last): File "/home/mathavan/.local/bin/DCC", line 33, in sys.exit(load_entry_point('DCC==0.5.0', 'console_scripts', 'DCC')()) File "/home/mathavan/.local/lib/python3.10/site-packages/DCC-0.5.0-py3.10.egg/DCC/main.py", line 490, in main File "/home/mathavan/.local/lib/python3.10/site-packages/DCC-0.5.0-py3.10.egg/DCC/main.py", line 679, in findCircSkipJunction File "/home/mathavan/.local/lib/python3.10/site-packages/DCC-0.5.0-py3.10.egg/DCC/Circ_nonCirc_Exon_Match.py", line 281, in findcircAdjacent File "/home/mathavan/.local/lib/python3.10/site-packages/DCC-0.5.0-py3.10.egg/DCC/Circ_nonCirc_Exon_Match.py", line 222, in getAdjacent ValueError: invalid literal for int() with base 10: '8"'

Hi @mathavanpu,

This error seems to have been caused by an update to HTSeq. I've corrected the code in DCC to correctly work with newer HTSeq versions.

Please reinstall from GitHub and see if the error is fixed for you.

Hi @tjakobi

I'm having the same issue as mentioned above:

Count CircSkip junctions Traceback (most recent call last): File "/usr/local/bin/circtools", line 18, in import circtools File "/usr/local/lib/python3.9/dist-packages/circtools/init.py", line 2, in main() File "/usr/local/lib/python3.9/dist-packages/circtools/circtools.py", line 31, in main CircTools() File "/usr/local/lib/python3.9/dist-packages/circtools/circtools.py", line 77, in init getattr(self, args.command)() File "/usr/local/lib/python3.9/dist-packages/circtools/circtools.py", line 609, in detect DCC.main(parser) File "/usr/local/lib/python3.9/dist-packages/DCC/main.py", line 490, in main CircSkipfiles = findCircSkipJunction(output_coordinates, options.tmp_dir, File "/usr/local/lib/python3.9/dist-packages/DCC/main.py", line 679, in findCircSkipJunction circStartAdjacentExons, circStartAdjacentExonsIv = CCEM.findcircAdjacent(circStartExons, Custom_exon_id2Iv, File "/usr/local/lib/python3.9/dist-packages/DCC/Circ_nonCirc_Exon_Match.py", line 281, in findcircAdjacent interval = Custom_exon_id2Iv[self.getAdjacent(ids, start=start)] File "/usr/local/lib/python3.9/dist-packages/DCC/Circ_nonCirc_Exon_Match.py", line 222, in getAdjacent exon_number = int(custom_exon_id.split(':')[1]) - 1 ValueError: invalid literal for int() with base 10: '2"'

It indeed seems that the HTSeq module is adding unwanted quotes to the modified GTF file. Is it possible to add this fix to the PyPi installation files?

Thanks Jasper

Hi @jaanckae,

Thank you for your report.

Are you using the master branch or a released PyPi version?

I did not yet publish a new DCC release yet, but will do so soon.

Could you please give the master branch version a try?

Thank you!

Hi @tjakobi

Master branch works perfect, thank you. On to the next part of the program.

@tjakobi do you plan to release a new version with this bug fix?

[tjakobi]

Hi @kelly-sovacool,

DCC is now part of circtools at https://github.com/jakobilab/circtools and this repository is not updated anymore.

The issues has been fixed in circtools which is available via pip or from GitHub.

Best,

Tobias
