Hi Endoh-san,

What version of bioruby library are you using?

Based on the history at github
https://github.com/bioruby/bioruby/commits/master/lib/bio/db/fastq.rb
the mask method was defined on August 11, 2010.
So, any prior version does not define the method mask, but later  
versions
like 1.4.1 should have the method.

> p entry.format   returns nil


In the rdoc you mentioned, select Bio::Fastq
in the upper middle column and you will find the following explanation:

format()
Format name. One of “fastq-sanger”, “fastq-solexa”, “fastq- 
illumina”, or nil (when not specified).

Returns:(String or nil) format name

So, getting nil for unspecified format seems what is expected.
