IQ-TREE key features

IQ-TREE - Efficient Tree Reconstruction

A fast and effective stochastic algorithm to infer phylogenetic trees by maximum likelihood. IQ-TREE compares favorably to RAxML and PhyML in terms of likelihoods with similar computing time (Nguyen et al., 2015).

ModelFinder - IQ Option官网 IQ Option官网 Fast and Accurate Model Selection

ModelFinder (Kalyaanamoorthy et al., 2017) enables a free rate variation model and is 10 to 100 times faster than jModelTest and ProtTest. It also finds best-fit partitioning scheme like PartitionFinder.

UFBoot - Ultrafast Bootstrap Approximation

UFBoot provides approximately unbiased branch support values and runs 100X faster than nonparametric bootstrap and 10 to 40 times faster than RAxML rapid bootstrap (Minh et IQ Option官网 al., 2013).

Big Data Analysis

Supporting huge datasets with thousands of sequences or millions of alignment sites via checkpointing, safe numerical and low memory mode. Multicore CPUs and parallel MPI system are utilized to speedup analysis.

Version 2.0 Highlights

  • Input alignment (-s option) or partition (-p) IQ Option官网 can be a directory of alignment files
  • Inference of rooted trees using non-reversible models
  • Faster tree search under topological constraint (-g option)
  • Gene/locus trees inference (-S option) and concordance factor analysis (--gcf) between DNA, protein and IQ Option官网 codon models (--modelomatic option) (--symtest option) (--tbe option)
  • Site rate estimation by maximum likelihood (--mlrate option) for partitioned models

IQ-TREE supports a wide range of evolutionary models

Common Models

All common substitution models for DNA, protein, codon, binary and morphological data with rate heterogeneity among sites.

Partition Models

Phylogenomic IQ Option官网 partition models allowing for mixed data types, mixed rate IQ Option官网 heterogeneity types, linked or unlinked branch lengths.

Mixture Models

IQ-TREE is user-friendly and well-documented

How to cite?

To maintain IQ-TREE, support users and secure fundings, it is IQ Option官网 important for us that you cite the following papers, whenever the corresponding features were applied for your analysis. Note that the paper of Nguyen et al. (2015) only described the tree search algorithm. Thus, it is not enough to only cite this paper if you, IQ Option官网 for example, use partition models, where Chernomor et al. (2016) should be cited.

Great app to use during the day. they have great online support.If you loss any money it's a mistake you made yourself.I've read some of this reviews on here people making IQ option sound bad.If you don't trust them yet then facebook me personally i dont work for them or anything.I'll be honest with you

@IQOption Great site, trustworthy and reliable. Have made IQ Option官网 about £3,600 and will continue to trade here.

Excellent interface. Great support - shoutout to Alex :) Only problem is that the risk exposure (i.e. maximum purchaseable product) is not forthcoming. Took me months before I figured it out but by then I'd made losses. As such, I only trade EUR/USD as it regularly gives the highest risk exposure (about 2.5k).

Withdrawals have had no issue for me at all. It was a painful process to set up (e-wallet, sending bank card details, passport details, drivers' licence. ), but once done, everything is pretty smooth. Ideal case is to deposit from a card, withdraw to a card, withdraw to the e-wallet and then withdraw from IQ Option官网 the e-wallet back to the card (especially if you're in a country that's not 'supported' by the e-wallet).
