1. COCO: Save the correct COCO figure; use the invpretile function to calculate percentiles;
2. eCOCO: Save data in an Excel file;
3. Curve Fitting: estimate the optimal span using the Generalized Cross-Validation (GCV) method;
4. Japanese version is ready (Thank Prof. Masayuki Ikeda);
5. CENOGRID (Westerhold et al., 2020, Science, doi: 10.1126/science.aba6853);
6. Dynamic filter: bug-free;
7. Insolation/astronomical solutions: debug. Start from 0. Thanks, Lucas Lourens!
8. Undatable: Age-depth modeling in Matlab.
    Thank Lougheed, B. C. and Obrochta, S. P. for permission.

9. Prof. Graham Weedon's SWA method included! Thank Graham!
            The spectrum is derived from a periodogram based on the Lomb-Scargle algorithm - allowing analysis of data with varying sample intervals in time_ml/distance or data with a fixed sample interval but data missing. Weedon et al. (2019) introduced the use of SWA as a non-parametric method for locating the spectral background. false_ml Discovery rates (FDR) are designed to control type I errors (false_ml positive detection of significant spectral peaks) while minimizing type II errors (false_ml rejection of spectral peaks as significant). Weedon (2020) illustrated multiple cases from cyclostratigraphy using SWA and FDR. Weedon (2022) investigated the associated false_ml detection rates.
10. MTM + SWA method (NEW);
11. Principal Component: language debug.

Acycle 2.6 Matlab

Acycle software has been upgraded to version 2.6 (www.acycle.org).

The most important upgrade is that the graphic user interface of Acycle 2.6 can be displayed using multiple languages.
In addition, lots of fantastic tools have been added/updated:

1. Newly designed Plot Pro GUI: easy to plot multi-panel, publish-quality figures.
2. Recurrence plot (NEW).
3. Main Window - Unit Listbox: add more options for unit selection.
4. Image profile to extract color series: allows more than two control points, and supports grayscale, CIE Lab, and RGB images.
5. Multiple languages are available: now Simpled Chinese and traditional Chinese versions are included to celebrate the Spring Festival, the most important festival in China and several other Asian countries. More languages are coming.
   [汉化版（简体中文和繁体中文）上线。]

Acycle v1.2 released!

What's new

Website: https://github.com/mingsongli/acycle;

Download: https://github.com/mingsongli/acycle#download;

Getting Started: https://github.com/mingsongli/acycle/wiki/3.-Getting-Started;

Acycle v1.2 has new stuff:

Date: May 20, 2019

• Signal/Noise generator: a GUI to replace old tools generating "sine wave", "red noise" and "white noise";

• Evolutionary spectral analysis: add one option for zero-padding both top and bottom of series, this is to add back the missed half-window due to the sliding window methods.

  • [Thank Dr. Nicolas R. Thibault (University of Copenhagen, Denmark) for this wonderful suggestion.]

• Evolutionary spectral analysis: add sub-panels showing 2-pi-MTM power spectrum and data-series

  • [Thank Daniel R. Franco (Department of Geophysics, National Observatory, Brazil) for this wonderful suggestion.]

• Support SPACE in file name and folder name;

  • [Thank Dr. Feng Cheng (Earth and Environmental Sciences, University of Rochester) for this suggestion.]

• COCO: detect test limits of sedimentation rate automatically.

Acycle v1.1 has new stuff:

• eCOCO: save optimal sed. rate as a text file: "*.ECOCO.Optimal.txt";

• eTimeOpt: save optimal sed. rate as a text file: "*.eTimeOpt.txt";

• TimeOpt and eTimeOpt use Taner roll-off rate of 1012 ;

• Put back lost smoothci.m and smoothciML.m files;

• Icons in the main window: remove borders of each button;

• Fix a bug in Plot Digitizer;

• Add a Mini-robot GUI.
