3146 Killed error #185

Open yu878 opened 3 years ago

yu878 commented 3 years ago

Hi there,

I have tried racon to do polishing of my data, although I got the following error. [racon::Polisher::initialize] loaded target sequences 10097.802500 s [racon::Polisher::initialize] loaded sequences 19.091033 s bash: line 11: 3146 Killed

I found a similar issue, but I don't know what the problem is. How can I solve it?

The command I use was this. racon -t 8 wtdbg_TE.fa TE_bowtie.sam TE.fq > TE_racon.fasta

Best regards, Yu

Hi Yu, Does the computer you are using have enough RAM to store all the data you are loading with Racon?

Best regards, Ivan.

Hi Ivan,

Thank you for your replying. I think there is enough RAM to store them, but I also tried racon-wrapper and got another error like the following.

[RaconWrapper::run] preparing data with rampler [RaconWrapper::run] total number of splits: 2714 [RaconWrapper::run] processing data with racon [racon::Polisher::initialize] loaded target sequences 1.836208 s [racon::Polisher::initialize] loaded sequences 17.155740 s [racon::Polisher::initialize] loaded overlaps 10015.492108 s [racon::Overlap::find_breaking_points] error: overlap is not transmuted! [racon::Overlap::find_breaking_points] error: overlap is not transmuted! [racon::Overlap::find_breaking_points] error: overlap is not transmuted! [racon::Overlap::find_breaking_points] error: overlap is not transmuted!

Did this error occur due to the limits of RAM or another problem?

Best regards, Yu

Hi Yu, error overlap is not transmuted means you run the command wrong. Run racon (or racon_wrapper) with racon <reads> <overlaps> <backbone>. In your first command racon -t 8 wtdbg_TE.fa TE_bowtie.sam TE.fq > TE_racon.fasta you passed the reads and backbone the other way around, although the first error indicates that you run out of memory.

Hi Robert,

Thank you for your replying. I tried racon -t 8 TE_racon.fasta TE.fq > TE_bowtie.sam and got an error again like following. [RaconWrapper::run] preparing data with rampler [RaconWrapper::run] total number of splits: 0 [RaconWrapper::run] error: unable to find split target sequences!

I am not sure why this error happened. For TE.fq, I used Illumina short read. I am sorry for my poor understanding but hope you can help me.

Best regards, Yu

Can you check out what is the length of the biggest contig in TE_racon.fasta? If not, check out the file size, divide id by 3 and use that number instead of <put length here>. Use the wrapper like this:

racon_wrapper -t 8 --split <put length here> TE.fq TE_bowtie.sam TE_racon.fasta > result.fasta

Hi Robert,

I tried it by using the number of the length of the biggest contig, but I also got the same error.

[RaconWrapper::run] preparing data with rampler [RaconWrapper::run] total number of splits: 0 [RaconWrapper::run] error: unable to find split target sequences!

I hope you could help me to solve this error.

Best regards, Yu
