Command line arguments

   Mandatory qualifiers (* if not always prompted):
  [-scopin]            infile     Name of scop classification file (embl
                                  format input)
   -mode               menu       Select number
*  -thresh             float      The % sequence identity redundancy threshold
*  -threshlow          float      The % sequence identity redundancy threshold
                                  (lower limit)
*  -threshup           float      The % sequence identity redundancy threshold
                                  (upper limit)
  [-scopout]           outfile    Name of non-redundant scop classification
                                  file (embl format output)
   -errf               outfile    Name of log file for the build

   Optional qualifiers:
   -datafile           matrixf    This is the scoring matrix file used when
                                  comparing sequences.
   -gapopen            float      The gap insertion penalty is the score taken
                                  away when a gap is created. The best value
                                  depends on the choice of comparison matrix.
                                  The default value assumes you are using the
                                  EBLOSUM62 matrix for protein sequences, and
                                  the EDNAFULL matrix for nucleotide
                                  sequences.
   -gapextend          float      The gap extension, penalty is added to the
                                  standard gap penalty for each base or
                                  residue in the gap. This is how long gaps
                                  are penalized. Usually you will expect a few
                                  long gaps rather than many short gaps, so
                                  the gap extension penalty should be lower
                                  than the gap penalty. An exception is where
                                  one or both sequences are single reads with
                                  possible sequencing errors in which case you
                                  would expect many single base gaps. You can
                                  get this result by setting the gap open
                                  penalty to zero (or very low) and using the
                                  gap extension penalty to control gap
                                  scoring.

   Advanced qualifiers: (none)
   General qualifiers:
  -help                boolean    Report command line options. More
                                  information on associated and general
                                  qualifiers can be found with -help -verbose


Mandatory qualifiers Allowed values Default
[-scopin]
(Parameter 1)
Name of scop classification file (embl format input) Input file Escop.dat
-mode Select number
1 (Remove redundancy at a single threshold % sequence similarity)
2 (Remove redundancy outside a range of acceptable threshold % similarity)
1
-thresh The % sequence identity redundancy threshold Any numeric value 95.0
-threshlow The % sequence identity redundancy threshold (lower limit) Any numeric value 30.0
-threshup The % sequence identity redundancy threshold (upper limit) Any numeric value 90.0
[-scopout]
(Parameter 2)
Name of non-redundant scop classification file (embl format output) Output file Escop_90.dat
-errf Name of log file for the build Output file scopnr.log
Optional qualifiers Allowed values Default
-datafile This is the scoring matrix file used when comparing sequences. Comparison matrix file in EMBOSS data path EBLOSUM62
-gapopen The gap insertion penalty is the score taken away when a gap is created. The best value depends on the choice of comparison matrix. The default value assumes you are using the EBLOSUM62 matrix for protein sequences, and the EDNAFULL matrix for nucleotide sequences. Floating point number from 1.0 to 100.0 10.0 for any sequence
-gapextend The gap extension, penalty is added to the standard gap penalty for each base or residue in the gap. This is how long gaps are penalized. Usually you will expect a few long gaps rather than many short gaps, so the gap extension penalty should be lower than the gap penalty. An exception is where one or both sequences are single reads with possible sequencing errors in which case you would expect many single base gaps. You can get this result by setting the gap open penalty to zero (or very low) and using the gap extension penalty to control gap scoring. Floating point number from 0.0 to 10.0 0.5 for any sequence
