Helicos sequencing analysis

[anle]

Hi,
I have downloaded a set of sra files from Helicos sequencing data and I wonder hw to proceed analyzing them. I found these tools provided from the company

but if I am nt mistaken they need input in sms format. Is there any way to transform .sra to .sms? Or in general is there any other way to analyze helicos data
