error occur while perform the assembly creation using trinity.

[Usha]

i am run this command.

/mnt/e/DenovoRNAseq/TOOLS/Trinityrnaseq-v2.6.6/Trinity --seqType fa --left left.fasta --right right.fasta --max_memory 5G --CPU 3 --output Trinity_output.dnv

it show the error.

Error, pairs.K25.stats is empty.  Be sure to check your fastq reads and ensure that the read names are identical except for the /1 or /2 designation. at /mnt/e/DenovoRNAseq/TOOLS/Trinityrnaseq-v2.6.6/util/insilico_read_normalization.pl line 921.
