I am very happy with the way I read my sequences and I would not change it
for any other method that I know.
Is as follows: A computer terminal is set on a table which has a built-in
light box. The table and light box area are large so the terminal can be
to my left, the keyboard to my right and the iluminated autoradiogram in
front of me. So I put my right hand in the keyboard in such a way that each
one of the A,G,C and T are under one of my fingers. This way I dont need
to look at the keyboard or the monitor any more. Then, using my right hand
to guide myself through the sequence it flows (the sequence) directly
to the computer as fast as I can read it.
When I started to do this I had my doubts about the rate of mistakes. However,
I found that mistakes were less than when somebody else is reading an you are
typing. The effort...... it only takes what it takes to read it!!
The cost of it is what it takes to get a good carpenter to make your own
design of the "reading bench" assuming that you already have acomputer.
Of course The Human Genome Proyect may want to use other methods.....
