To calculate particular information for sequences Frequency 語法 : string substr (string string, int start [, int length]) 說明 : substr( ) 傳回 string 的一部份字串，由參數 start 和 length 指定。 如果 start 是正數，傳回的字串將會從 string 的第 start 個字元開始。 Example : <?php $rest = substr ("abcdef", 1); // returns "bcdef" $rest = substr ("abcdef", 1, 3); // returns "bcd" ?> 如果 start 是負數，傳回的字串將會從 string 結尾的第 start 個字開始。 44

To calculate particular information for sequences CG% Length 語法 : int strlen (string str) 說明 : 傳回字串 str 的長度 。 Example : <?php $DNA_length=strlen($a); ?> 45

Translate the nucleotide to amino acid $codons = substr ($sequence, $first, $first+2); 46

Submit a sequence to blast by the interface GRAMS=megaBlast&PAGE_TYPE=BlastSearch&SHOW_DEFAULTS= on&LINK_LOC=blasthome 47
