Protein sequence manipulation for adding elements before or after the sequence.
显示 更早的评论
how do i add zeros to both ends or one end (before or after) of a protein sequence?
Example:
a protein sequence is given as 'ITYTDCTESGQDLCLCEGSDVCGKGNKCILGSNGEENQCVTGEGTPKPQSHNDGDFEEIPEEYLQ'
how do i add zeros at the beginning before the first element of the sequence?

The easiest way to add N zeros before it can be done by:
[repmat('0', 1, N) yourProSeq];

Why didn't you give a try? by a row of sequence, it could either be a char array or a string. no matter what, it works this way.
char array
>> mm = 'ACGTACGT'
mm =
'ACGTACGT'
>> [repmat('0', 1, 10) mm]
ans =
'0000000000ACGTACGT'
string
>> mm = "ACGTACGT"
mm =
"ACGTACGT"
>> repmat('0', 1, 10)+mm
ans =
"0000000000ACGTACGT"

You flip the repmat() stuff and mm in above example.
