I work with GeneChips to analyze human gene expression
patterns. These genechips are various kinds one of the
variety is made at Stanford University. In a typical
experiment, an experimenter uses roughly over 40
For a third party to analyze data from that chip, we
should know the design of that chip and that
information is one file. In this case it is GAL file.
Since it is difficult and cumbersome to identify each
design file type of all chips and get it into your
directory. However, on their website SMD
(http://genome-www5.stanford.edu/), it is possible to
go to each design file and obtain the data. Since
this is a time taking procedure, I wrote a socket
script that would give me the URL of the file and
allowing me to download. The first barrier is, their
database does not allow sockets programming.
Unfortunately, I have to access each file (there could
be 40 - 100 files), get redirected to another page and
there I can be able to download.
Is there a method to automate this procedure through a
Is there any alternative for such clicks.
In this page at the bottom there is a link to
'Generate GAL file', that URL will allow me to get GAL
I cannot sit for whole evening and click ~40x30 times
and download that. It is painful. Are there any smart
ways to hack this process.
