Thank you for trying RAPT! SRS10489852 is the identifier for a sample, which corresponds to multiple SRA experiements and runs. RAPT takes runs as input, with identifiers starting with the letters SRR, ERR or DRR. In addition, these runs must be of short reads (Illumina).
See SRS10489852. Several experiments are linked to this sample, but the only one that was generated with an Illumina instrument is experiment SRX12530589/run SRR16250963 . Please try running RAPT with SRR16250963 and let us know how it goes.

I tried running RAPT on SRR16250963. Unfortunately, the run failed in the assembly step. I suspect this is because this sample is a mixture. If you look in the analysis tab of this page, out of the 25% of reads that can be identified, 60% are predicted to be bacterial and most of the rest is eukaryotic.
