V is an average timecourse of these neurons, e.g. component time course.\n\nYou can install EnsemblePursuit with \"pip install EnsemblePursuit\"\n\nFor more details see the  [wiki](https://github.com/mariakesa/EnsemblePursuit/wiki) and our [Statistical Analysis of Neural Data 2019 workshop poster](https://github.com/mariakesa/EnsemblePursuit/blob/master/sand_poster2019.pdf)\n\n![Alt Text](https://github.com/MouseLand/EnsemblePursuit/blob/master/Figures/my_gif.gif)\n\nEnsembles learned using EnsemblePursuit from recordings in V1 have Gabor receptive fields. \n\n![alt text](https://github.com/mariakesa/EnsemblePursuit/blob/master/Figures/ep_rec_fields.png)\n\nSome ensembles are well explained by behavior PC's extracted from mouse orofacial movies.\n\n![](https://github.com/mariakesa/EnsemblePursuit/blob/master/Figures/mouse.gif)\n\n\n![alt text](https://github.com/mariakesa/EnsemblePursuit/blob/master/Figures/Behavior.png)\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmouseland%2Fensemblepursuit","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmouseland%2Fensemblepursuit","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmouseland%2Fensemblepursuit/lists"}
