I have been downloading a lot of NCBI short read archive files (.sra files) and I know how to convert them to bam, sam, fastq, etc but is there a way to generate my own .sra files? The tools in the SRA toolkit do not seem to convert to .sra

​Relevant Information:

 - [SRA toolkit][1]
 - [Handbook][2]
