NAME

       RNAeffective - calculation of effective numbers of orthologous miRNA targets

SYNOPSIS

       RNAeffective  [-h]  [-d  frequency_file]  [-f  from,to] [-k sample_size] [-l mean,std] [-m
       max_target_length] [-n max_query_length]  [-u  iloop_upper_limit]  [-v  bloop_upper_limit]
       [-s] [-t target_file] [-q query_file] [query]

DESCRIPTION

       RNAeffective  is a tool for determining the effective number of orthologous miRNA targets.
       This number can be used for the calculation of more  accurate  joint  p-values  in  multi-
       species  analyses. RNAeffective searches a set of target sequences with random miRNAs that
       can be given on the command line or otherwise  generates  random  sequences  according  to
       given  sample  size,  length  distribution  parameters  and  dinucleotide frequencies. The
       empirical distribution of joint p-values is compared to the p-values themselves,  and  the
       effective  number of independent targets is the one that reduces the deviation between the
       two distributions.

OPTIONS

       -h     Give a short summary of command line options.

       -d frequency_file
              Generate  random  sequences  according  to  dinucleotide   frequencies   given   in
              frequency_file. See example directory for example files.

       -f from,to
              Forces  all  structures  to  have  a  helix  from position from to position to with
              respect to the query. The first base has position 1.

       -k sample_size
              Generate sample_size random sequences. Default value is 5000.

       -l mean,std
              Generate random sequences with a  normal  length  distribution  of  mean  mean  and
              standard deviation std. Default values are 22 and 0, respectively.

       -m max_target_length
              The  maximum  allowed  length of a target sequence. The default value is 2000. This
              option only has an effect if a target file is given with the -t option (see below).

       -n max_query_length
              The maximum allowed length of a query sequence.  The  default  value  is  30.  This
              option only has an effect if a query file is given with the -q option (see below).

       -u iloop_upper_limit
              The  maximally allowed number of unpaired nucleotides in either side of an internal
              loop.

       -v bloop_upper_limit
              The maximally allowed number of unpaired nucleotides in a bulge loop.

       -s     Generate random sequences according  to  the  dinucleotide  distribution  of  given
              queries  (either with the -q option or on command line. If no -q is given, the last
              argument to RNAeffective is taken as a query). See -q option.

       -q query_file
              Without the -s option, each of the query sequences  in  query_file  is  subject  to
              hybridisation  with  each  of  the  targets (which are from the target_file; see -t
              below). The sequences in the query_file have to be in FASTA format,  ie.  one  line
              starting with a > and directly followed by a name, then one or more following lines
              with the sequence itself. Each individual sequence line must  not  have  more  than
              1000 characters.

              With the -s option, the query (or query file) dinucleotide distribution is counted,
              and random sequences are generated according to this distribution.

              If no -q is given, random sequences  are  generated  as  described  above  (see  -d
              option).

       -t target_file
              See -q option above.
