ERROR : [process_sams.py:108:preprocess_sam] when running talon #152

I have the same problem. Have you solved it? |
Hi, I used a conda environment to run talon. I downgraded pysam and it worked for me properly. My previous version of pysam is 0.22.1. Then I installed 0.21.0. Everything was going well. |
Ok, thank you for your reply. I will try it according to your method. Thank you very much! |
Hi, if this solution doesn't work for you. Another way is to delete your database, then run talon_initialize_database again to initiate your database again. I failed to run talon step due to memory issue. When I rerun it, I got this ERROR. I deleted my database and run talon_initialize_database again. Then everything is going well. |
I appreciate your prompt reply, although I don't know why I did it. But I will try the solution you gave me. Thank you very much for your detailed reply! |

Hi！when i run the code |
|
talon_config.csv contains your sam file, you need to check if your sam file path is correct.

Hi！when i run the code
talon \ --db talon.db \ --f talon_config.csv \ --threads 10 \ --build ini_talon_hg38 \ --cov 0.99 \ --identity 0.95 \ --o /data/work/temp/talon_anno,the error says
SAM/BAM file 'sam_file' does not exist!

Hi, thanks for developing TALON for long-read RNA-seq analysis.
I was working on the ONT direct RNA-sequencing data. Following the tutorial, I ran talon but there was an ERROR about sam files.
Here is the ERROR I got:

The version of TALON I installed is v6.0. The version of samtools is 1.3.1. I also checked the header of my TALON labeled sam file where I can find the headers. Do you know what is the problem I got? Many thanks for any help!
Best,
