gnuplot is not an especially powerful data processing language, I agree external utilities would be a good idea for this. Perhaps awk or perl.
Could you show a sample of your input data, and a sample of the output you'd want?

Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:
for example plot filename.txt
It says that (.txt ) is not identified ... I tried to write it without the .txt part, but I also get the error msg.
Any idea why? :confused: (1 Reply)

Dotur(1) General Commands Manual Dotur(1)
NAME
dotur - A program for calculating descriptive statistics for sequence libraries
SYNOPSIS
dotur [-i Iterations (<1000>)] [-c ClusterMethod (<f>, n, a)] [-p Precision (10, <100>, 1000, 10000)] [-l] [-j] <file>
OPTIONS
-i: Number of iterations (default = 1000)
-c: Clustering method - (f) furthest neighbor, (n) nearest neighbor, (a) average neighbor (default = f)
-p: Precision of distances for output, increasing can dramatically lengthen execution times - 10, 100, 1000, 10000 (default = 100)
-l: Input file is lower triangular (default = square matrix)
-r: Calculates rarefaction curves for each parameter, can dramatically lengthen execution times. Simple rarefaction curve always calcu-
lated.
-stop: Stops clustering when cutoff has been reached.
-wrep: Samples with replacement.
-jumble:
Jumble the order of the distance matrix.
-sim: Converts similarity score to distance (D=1-S).
DESCRIPTION
This is the Debian GNU/Linux version of dotur.
DOTUR is a computer program that takes a distance matrix describing the genetic distance between DNA sequence data and assigns sequences to
operational taxonomic units (OTUs) using either the furthest, average, or nearest neighbor algorithms for all possible distances that can
be described using the distance matrix. Using the OTU composition data, DOTUR constructs collector's and rarefaction curves for sampling
intensity, richness estimators, and diversity indices.
