- The window
- The field
**"from"**serves for definition of number of a position of a sequence 1 with which search begins. - The field
**"to"**serves for definition of number of a position of a sequence 1 on which search comes to an end. - The field
**"length"**serves for definition of length of area of search. - The field
**"mismatch"**serves for set allowable quantity of discrepancies by search. If the field is not filled, to parameter value 0 automatically is appropriated. Restrictions on quantity of discrepancies: no more than half of length of motif, and also no more than 1000. - The field
**"Command summary"**displays the current adjustments of a command (the chosen parameters). The given field is only information and does not serve for adjustment of parameters of command.

- Parameters "from", "to" and "length" are connected among themselves. Simultaneously can be given no more than two parameters. At recalculation of parameters there is a check that values of parameters do not contradict each other and are intelligent.
- If parameters "from", "to" and "length" are not given, to parameter "from" value "BEGIN" is appropriated (the beginning of a sequence), to parameter "To" is appropriated value "END" (the end of a sequence).
- If the parameter "length" is given only, to parameter "to" value "BEGIN" is appropriated (the beginning of a sequence), to parameter "to" value of parameter "length" is appropriated.
- If the parameter "to" is given only, to parameter "from" value "BEGIN" (the beginning of a sequence) is appropriated.
- If the parameter "from" is given only, to parameter "to" value "END" (the end of a sequence) is appropriated.
- If parameters "from" and "length" are given, value "to" is calculated in view of the specified values (to=from length-1).
- If parameters "to" and "length" are given, value "from" is calculated in view of the specified values (from=to-lenhgth+1).
