Section 7-2: Enter Your Sequence from Scratch

[ Previous chapter ][ This chapter ][ Next chapter ]

Start of the 'seqed' Program

% seqed

You will then be prompted for the name of the sequence you want to edit. Do this by responding to the question

 

  
what file?
  

  

If you have any additional, non-sequence information, such as reference or author information, type the text into the field you find the cursor (the top 4 lines of the screen). There, you should enter any annotation or reference needed to characterise the sequence. Then, exit this mode (which is called heading mode) with

<CTRL><D>

You are now on the sequence line, so enter the sequence. The sequence will appear character by character as you type it. This mode is the so-called screen mode. When completed, go to the command mode with the command

<CTRL><D>

There, give the command 'exit' as follows:

<CTRL><D>

: exit

================================= Begin Exercise 2

A small 'seqed' exercise: Type in a DNA sequence.

Use the sequence editor 'seqed' and type in the following sequence. Name it "my1.seq" - we will need this sequence in later exercises.
