Go to the output files for this example
Standard (Mandatory) qualifiers (* if not always prompted):
[-sequence] seqall Nucleotide sequence(s) filename and optional
format, or reference (input USA)
-windowsize integer [20] The values of melting point and other
thermodynamic properties of the sequence are
determined by taking a short length of
sequence known as a window and determining
the properties of the sequence in that
window. The window is incrementally moved
along the sequence with the properties being
calculated at each new position. (Integer
from 1 to 100)
-shiftincrement integer [1] This is the amount by which the window
is moved at each increment in order to find
the melting point and other properties along
the sequence. (Integer 1 or more)
-dnaconc float [50.] Enter DNA concentration (nM) (Number
from 1.000 to 100000.000)
-saltconc float [50.] Enter salt concentration (mM) (Number
from 1.000 to 1000.000)
* -mintemp float [55.] Enter a minimum value for the
temperature scale (y-axis) of the plot.
(Number from 0.000 to 150.000)

(ps, hpgl, hp7470, hp7580, meta, cps, x11,
tekt, tek, none, data, xterm, png, gif)
* -outfile report [*.dan] If a plot is not being produced then
data on the melting point etc. in each
window along the sequence is output to the
file.
Additional (Optional) qualifiers (* if not always prompted):
-product toggle This prompts for percent formamide, percent
of mismatches allowed and product length.
* -formamide float [0.] This specifies the percent formamide to
be used in calculations (it is ignored
unless -product is used). (Number from 0.000
to 100.000)
* -mismatch float [0.] This specifies the percent mismatch to
be used in calculations (it is ignored
unless -product is used). (Number from 0.000

(it is ignored unless -product is used).
(Any integer value)
-thermo toggle Output the DeltaG, DeltaH and DeltaS values
of the sequence windows to the output data
file.

values. (Number from 0.000 to 100.000)
Advanced (Unprompted) qualifiers:
-rna boolean This specifies that the sequence is an RNA
sequence and not a DNA sequence.

melting point along the sequence is
produced.

The output is a standard EMBOSS report file.
The results can be output in one of several styles by using the command-line qualifier -rformat xxx, where 'xxx' is replaced by the name of the required format. The available format names are: embl, genbank, gff, pir, swiss, trace, listfile, dbmotif, diffseq, excel, feattable, motif, regions, seqtable, simple, srs, table, tagseq
See: http://emboss.sf.net/docs/themes/ReportFormats.html for further information on report formats.
By default dan writes a 'seqtable' report file.

The header information contains details of the program, date and sequence
Subsequent lines contain columns of data for each window into the sequence as it is moved along, giving:
If the qualifier '-product' is used to make the program prompt for percent formamide percent of mismatches allowed and product length, then the output includes the melting temperature of the specified product.
If the qualifier '-thermo' is gived then the DeltaG, DeltaH and DeltaS of the sequence in the window is also output.
EMBOSS data files are distributed with the application and stored in the standard EMBOSS data directory, which is defined by the EMBOSS environment variable EMBOSS_DATA.
To see the available EMBOSS data files, run:
% embossdata -showall
To fetch one of the data files (for example 'Exxx.dat') into your current directory for you to inspect or modify, run:
% embossdata -fetch -file Exxx.dat
Users can provide their own data files in their own directories. Project specific files can be put in the current directory, or for tidier directory listings in a subdirectory called ".embossdata". Files for all EMBOSS runs can be put in the user's home directory, or again in a subdirectory called ".embossdata".
The directories are searched in the following order:
| Program name | Description |
|---|---|
| banana | Bending and curvature plot in B-DNA |
| btwisted | Calculates the twisting in a B-DNA sequence |
| chaos | Create a chaos game representation plot for a sequence |
| compseq | Count composition of dimer/trimer/etc words in a sequence |
| freak | Residue/base frequency table or plot |
| isochore | Plots isochores in large DNA sequences |
| sirna | Finds siRNA duplexes in mRNA |
| wordcount | Counts words of a specified size in a DNA sequence |
