What they say?

I am writing to express my appreciation for all the hard work and thought that has gone into the development of the Acycle software program. It is truly an amazing contribution to the geosciences community. As someone who has spent much of the last 50 years trying to understand cyclic carbonates on shallow platforms, and having been involved with my students in some of the early work on stratigraphic modelling of the effects of Milankovitch forcing of carbonate platform stratigraphy, I was blown away by the power of the Acycle software.
In the old days we used in house programs from our geophysicist Cahit Coruh, and recently I have used Analyseries, kSpectra and Timefrq43, moving from Dos to Windows to Mac, jumping from one to the other to get the job done. Acycle has done away with the need for this, and I have been impressed with how very user friendly the program is – an indication of the tremendous effort and thought that has gone into putting this together.
You should all feel very proud of this contribution. It opens up much needed access to these powerful tools for a wide audience in the sedimentary geology and paleoclimate community. Thanks again for all your efforts. A really marvellous job.

"Mingsong Li's Acycle software enables us to quickly analyze the potential of new outcrops and boreholes, and then to determine the sedimentation rates and elapsed time. His Acycle software will become the standard tool for time-scale applications by all international workers."
Dr. Paul E. Olsen
(Professor of Earth and Environmental Sciences of Columbia University; Member, National Academy of Sciences of the USA):
"Not only is this software powerful and effective, it is also simple to use and therefore benefits researchers and at all levels within the paleoclimatology community, from novices to experts."
Dr. Marco Franceschi
(Department of Geosciences, University of Padova, Italy):
“Dr. Li’s software is being immensely valuable to my work. Some of the stratigraphic series I am studying display a prominent cyclicity, but were deposited in contexts characterized by relevant changes in sedimentation rates and often lack accurate geochronological constraints. Acycle has been designed specifically for dealing with similar cases, by tackling them with a rigorous statistical approach, and therefore is providing an invaluable tool for their investigation.”
Dr. Xu Yao
(School of Earth Sciences, Lanzhou University, China)
“I am working on cyclostratigraphy and paleoclimate study of ancient strata and rocks (270 million years ago) with assistance from Acycle software. I also introduced this software to my colleagues whose research areas are paleoclimate implications of Quaternary loess (several thousand years ago). My colleagues have given me really good feedbacks about Acycle software.”
Dr. Christian Zeeden
(IMCCE, Observatoire de Paris, France):
“Dr. Li’s software is novel and valuable in this context, especially because it facilitates the easy application of otherwise complex calculations.”
Dr. Arsenio Muñoz Jiménez
(Department of Earth Sciences, University of Zaragoza, Spain):
“Thank you very much and congratulations for the acycle software. I am using it and it is very very useful and interesting.”
Dr. Nicolas R. Thibault
(University of Copenhagen, Denmark):
“I’ve been playing a lot with the excellent Acycle package for Matlab that Mingsong developed. Congratulations, this is a very nice interface that simplifies a lot our work and makes it truly faster to analyse a time-series.”
