download just a chromosome from SRA toolkit

Question

[amahdi779]

I want to download samples.fastq from a special SRP in GEO but I don't know that is possible to download just a chromosome.fastq file or not.

Can I download particular part of fastq samples from a database(like from a whole genome bs-sequencing just download a chromosome)? For practice of bs-sequencing I want to work on bs-seq data that is important the amount of data and I must to work on small volume fastq file

Answer 1

No, it is not possible since fastq are raw data without alignment information, hence without chromosomal information.

Answer 2

No, its impossible. Sequencing reads in SRA are not partitioned by chromosomes.
