Error in sqanti_qc2.py about sqanti2

[Magdoll]

Hi @ljw90607 ,

Can you check that the .classification.txt and .junctions.txt are already written? This error is odd as it seems to be pertaining to the R script portion of the pipeline which should not be affected by the additional -c junction info.

If the .classification.txt and .junctions.txt files are already written, please try running:

python <path_to_SQANTI2>/utilities/SQANTI_report2.R  xxx.classifications.txt xxx.junctions.txt

and see if you can reproduce the error.

Thank you @Magdoll ,

The .classification.txt file is written, but also tmp file is present.
And .junctions.txt file with only the header is written (with no output), and also the tmp file is present

I did check the script you have provided, and got the following error

File "/appl/sqanti2/SQANTI2/utilities/SQANTI_report2.R", line 11
class.file <- args[1]
^
SyntaxError: invalid syntax

This error did not occur when I did not put the short read junction file in as a input.

Thank you so much for your help.

Dear @Magdoll ,

After few more test run for sqanti_qc2.py, I found that the junction.txt file is not being produced.
Also after the error, classification.txt file remained as classificatino.txt_tmp file.

What could have gone wrong?

Thank you very much for your help.

Hi @ljw90607 ,

I'm not sure why you are getting this error. The .junctions.txt files should be written.

In order to best help with debugging, please first update to the latest SQANTI2 through GitHub and re-run again. Note the error. If it's the same, I will ask you to send me the input files for debugging.

Dear @Magdoll

After reinstalling the tool and trying out few script run, I was able to run the sqanti_qc2.py.
But using the output (classification.txt and junctions.txt), I am getting no output (0 file size) for filtered.lite.fasta file.
I have used short read junction files to get the classification.txt and junctions.txt output.
Not sure why no output is being generated.
If you could help me with it, I would really appreciate it!

(I am getting about 50,000 reads for filtered.lite.reasons.txt)

Hi @ljw90607 ,

Please see how many entries you have in .classification.txt and what the reasons listed in filtered.lite.reasons.txt are. I wonder if all of them were filtered out for some reason.

Dear @Magdoll

Thank you for your comment.

Without using any options (using default) for the run,
I do get 1,378,410 rows of read information in .classification.txt file and 54,095 row of reads were filtered in filtered.lite.reasons.txt file due to low coverage, intrapriming, RT switching.

I tried with -c 10 and the log said 1122226 to be kept (and 250,000 reads filtered out), but still no output is being written.

Hi @ljw90607 ,
I think I know why you are not getting the output fasta. You probably gave it the wrong fasta with not the right seq IDs.

Please use the ".renamed.fasta" from the sqanti_qc.py output for the filtering step.

Dear @Magdoll

Thank you so much for your comment.
I have just ran sqanti_filter.py using the renamed.fasta and still did not get the output.

What I have actually noticed is that there were added information right after the isoform IDs in .classification.txt.
For example, in the .renamed.fasta, one of IDs are present as "55c76dab-0331-4dfa-9b79-a3cd1392b783|-". But in the .classification.txt, the same ID is shown as "55c76dab-0331-4dfa-9b79-a3cd1392b783%7C-". (%7C- as added letters)
Would this be the issue of why I am not able to get the output fasta file?
How could I match the IDs between .classification.txt and the fasta file.

Thank you so much again for your wonderful help.

Hi @ljw90607 ,

I think there's some weird symbols in your original FASTA file. Can you please clean up the original input fasta to use only IDs with format PB.X.Y or at least something like it?

Dear @Magdoll

Thank you for your wonderful help.

I am actually trying to run another sqanti_qc run using another input.
What could be the issue if the sqanti_qc run ends with the "error: data input empty"?
(no renamed.corrected.faa is being made)
I have used a filtered out fastq file as a input, but I cannot figure out why this is occurring.
The error message is shown as below.

Hi @ljw90607 ,

It is not possible to know the exact cause without looking at the data, but I suspect one possibility is all of your reads are unmapped? Hence there is no data to run SQANTI on.
