# Ribbon Bar Command: Export

The commands Export and Export all Simulations open a standard Windows File dialog box for specifying the path and the name of the file to which the data are exported. The first command exports only the active simulation while the second command starts a loop that enables the user to export all simulations involved in the active simulation document file by file. Two export filters are available:

Both the simulated current curve and the simulation parameters (electrode geometry and area, species concentration etc.) will be exported in use-format.

Description of the use-file format:

DigiElch_IMP_Header

experimental parameters:

key_word_1: Value_1

key_word_2: Value_2

.

.

species parameters:

[name of species_1] (M/l): Canal_1

[name of species_2] (M/l): Canal_2

.

.

experimental IMP-data:

number of ZI (Ohm), ZR (Ohm) couples: N

ZR_1 , ZI_1

ZR_2 , ZI_2

.

ZR_N , ZI_N

Signal Header

f_1 , Phi_1 , A_1

f_2 , Phi_2 , A_2

f_15 , Phi_15 , A_15

•DigiElch_IMP_Header

source program: DigiElch for Windows

program version: 3.0

file type: IMP

•key_word_i and Value_i

key word and value referring to the i-th parameter. The value must be in point-format and separated from the key word by a colon. The key words are the same as the parameter names used on the Property Page: Simulation Parameters. For example,

Pre-Equilibrium: smart

Diffusion: Semi-Infinite 1D

Geometry: Planar

Area (cm²): 1

Ru (Ohm): 0

Cdl (F): 0

Temp. (K): 298.2

dEac (V): 0.015

AC-Packets: 2

fmin (Hz): 100

fmax (Hz): 5050

log2(Data Points): 11

Applied Frequencies: 15

Estart (V):0.3

Edc (V):0

DC-Time (s):5

•name of species_i and Canal_i

the name of the i-th species in brackets and the analytical concentration in point-format. For example

[NiL] (M/l): 0.001

[NiL-] (M/l): 0

[DP] (M/l): 0.1

[NiLDP] (M/l): 0

[NiLDP-] (M/l): 0

•N

the number of Applied Frequencies.

•ZR_i and ZI_i

numbers (separated by comma) representing the real imaginary part of the impedance simulated for the i -th frequency component

•Signal Header

an abbreviation for the following line: signal components (f/fo, phase angle, rel. amplitude):

This line is followed by a description of the applied AC-Signal (which should always be defined for 15 frequency components even if the data refer to a smaller number of actually Applied Frequencies):

of_i

(relative) value of the i-th frequency component

oPhi_i

absolute value of the phase angle of the i-th frequency component

oA_i

relative value of the amplitude of the i-th frequency component

All relative values refer to the corresponding value of the basic frequency. It is the frequency which would be obtained if the signal formed by the 2n data points (where n is the number defined in log2(Data Points)) covers exactly a single sinus cycle.

Only the simulated current curve but not the simulation parameters (electrode geometry and area, species concentration etc.) will be exported in the following form:

•Option: Plot ZI vs. ZR

simulated data:

number of ZR (Ohm), ZI(Ohm) couples: N

ZR_1 separator ZI_1

ZR_2 separator ZI_2

. . .

. . .

ZR_N separator ZI_N

•Option: Plot Z vs. 1/sqrt(ω)

simulated data:

number of 1/sqrt(w (Hz)), ZI (Ohm), ZR(Ohm) triples: N

1/sqrt(w_1) separator ZI_1 separator ZR_1

1/sqrt(w_2) separator ZI_2 separator ZR_2

. . . . .

. . . . .

1/sqrt(w_N) separator ZI_N separator ZR_N

•Option: Plot cot(ϕ) vs. sqrt(ω)

simulated data:

number of sqrt(w (Hz)), cot(phi) couples:: N

sqrt(w_1) separator cot(Phi_1)

sqrt(w_2) separator cot(Phi_2)

. . .

. . .

sqrt(w_N) separator cot(Phi_N)

oN

the number of Applied Frequencies.

oZR_i and ZI_i

are the real imaginary part of the impedance simulated for the i-th frequency component.

ow_i

the absolute (real world) value of the i-th frequency component, f_i, multiplied by 2π

oPhi_i

the phase angle of the i-th frequency component.

oSeparator

one of the following characters: 'Space', 'Tab', 'Comma' or 'Semicolon'

Numbers can be formatted using either point or comma. The formatting of numbers and type the separator can be specified under Export Data (*.txt) on the Properties window.
