Assembling exited halfway - ERROR: No valid assembly graph found

[JianjunJin]

Take the liberty to borrow the post owner's place. I want to ask where my error occurred. It always occurs No valid Assembly graph found.@Kinggerm First, the code I used:get_organelle_from_reads.py -1 /home/mxx/anaconda3/envs/get/BR1_FDMS210380612-1a_1.clean.fq.gz -2 /home/mxx/anaconda3/envs/get/BR1_FDMS210380612-1a_2.clean.fq.gz -o test5 -R 32 -t 64 -F animal_mt --reduce-reads-for-coverage inf --max-reads inf log file: get_org.log.txt spades.log Please take a look at this when convenient to yourself.

Your issue is different from issue116. Please note that the spades assembly step exited almost immediately after the start. So you troubleshoot your environment to run spades normally.

The spades.log you provides is not the right one. Please provide the spades.log file under test5/extend_spades if it existed.

I think this may be a conda dependency issue.

With spades v3.13.0 the log looks like this

Command line: /mnt/shared/scratch/owhite/apps/conda/envs/getorgelle_conda_env/bin/spades.py     -t      1       --phred-offset  33      -1      /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_1_paired.fq -2      /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_2_paired.fq        --s1    /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_1_unpaired.fq       --s2    /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_2_unpaired.fq      -k      21,55,85,115    -o      /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_spades

System information:
  SPAdes version: 3.13.0
  Python version: 3.10.6
  OS: Linux-4.18.0-372.26.1.el8_6.x86_64-x86_64-with-glibc2.28

Output dir: /mnt/shared/home/owhite/test/getorganelle/results_directory/extended_spades
Mode: read error correction and assembling
Debug mode is turned OFF

Dataset parameters:
  Multi-cell mode (you should set '--sc' flag if input data was obtained with MDA (single-cell) technology or --meta flag if processing metagenomic dataset)
  Reads:

With spades version 3.15.5 it works as expected.

With my conda installation conda (```conda create --name getorganelle getorganelle````) I get spades 3.15.5. But with conda I get 3.13.0

Thanks for Ollie White's comments. This is the solution to the problem! Just update your SPAdes to version 3.15.5 (conda update SPAdes). It will work normally.

Hi, tried to do de novo assembly for Arabidopsis test data, during the process assembly existed halfway and received an error; No valid graph found. I have attached the log file herewith. Could you please help me to resolve the issue

收到，谢谢！

@Rajaratnam1234 Have you tried to install SPAdes from the source?

[Rajaratnam1234]

Thank you for your response. There was an error in python. I re_installed the package. Now assembling is working properly!
