RNA-seq data is single ended and distributed among different lanes. I am trying to assembel the transcriptome using this command:

trinity/trinityrnaseq-Trinity-v2.8.3/Trinity --seqType fq --max_memory 10G --single SRR3460466.fastq,SRR3460467.fastq,SRR3460468.fastq,SRR3460469.fastq,SRR3460470.fastq,SRR3460471.fastq,SRR3460472.fastq,SRR3460473.fastq,SRR3460474.fastq,SRR3460475.fastq,SRR3460476.fastq,SRR3460477.fastq

But I am getting this error

Error, not recognizing read name formatting: [SRR3460466.1]

If your data come from SRA, be sure to dump the fastq file like so:

    SRA_TOOLKIT/fastq-dump --defline-seq '@$sn[_$rn]/$ri' --split-files file.sra

Reading the error message carefully, you will see:

If your data come from SRA, be sure to dump the fastq file like so:

SRA_TOOLKIT/fastq-dump --defline-seq '@$sn[_$rn]/$ri' --split-files file.sra

I have used SRA_TOOLKIT/fastq-dump to dump the fastq files, since my data is single ended, do i still need to use --split-files as this option is used for paired ended data
