Here is a sample session with cutseq To remove bases 10 to 12 from a database entry and write to the new sequence file 'gatta2.seq': % cutseq tembl:paamir gatta2.seq -from=10 -to=12 Removes a specified section from a sequence. Go to the input files for this exampleGo to the output files for this example Example 2 To remove the first 20 bases from 'tembl:paamir' and write it to 'jsh.seq': % cutseq tembl:paamir -from=1 -to=20 -out=jsh.seq Removes a specified section from a sequence. Go to the output files for this example Example 3 If the default start and end positions are accepted, then all of the sequence is removed! % cutseq tembl:paamir starta.seq -sbeg=-1000 -send=1290 Removes a specified section from a sequence. Start of region to delete [1168]: End of region to delete [1290]: Go to the output files for this example
