How to get lesser contig number through SPAdes assembly. Plateform- illumina ,pair end reads 2*150 Also I am getting warnings as follows:

1. Estimated mean insert size 152.79 is very small compared to read length 150
2.The determined erroneous connection coverage threshold may be determined improperly

Hello sangita.sarma71991,

Please use the formatting bar (especially the code option) to present your post better. I've done it for you this time.

Also, you should add other information as well like

• organism name

• expected genome size

• kmer used in assembly

• total data that you have

• coverage of the data

Thank you!
