The window "Cut" serves to allocation of a fragment from a sequence or cutting out (deletion) of a fragment from a sequence. In heading after a mark "#" the dropping down list serves to a choice of an entering sequence is located.
The field "Result (sequence name)" serves to set a name of a resulting sequence. By default to sequences assign names: seq 1 , seq 2 etc. The given field should be obligatory filled.
The field "from" serves for definition of number of the first position of a fragment for sequences.
The field "to" serves for definition of number of last position of a fragment.
The field "length" serves for definition of a length of a fragment.
The panel "what to do" serves for definition of a kind of operation above a fragment:
"keep" - to leave only the given fragment
"delete" - to remove the given fragment from a sequence.
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.
Notes.
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).
