Description

Electron microscopic data label and its generation method and generation system
Technical field
The present invention relates to computer realm, more particularly to a kind of electron microscopic data label and its generation method and generation system.
Background technology
With the progress of hardware technology, using the structure of Ice mapping technology parsing large biological molecule becoming one it is fine New structure biology research direction.In recent years, many research teams are based on Ice mapping technology in international top academic journal Nature, Science, Cell etc. delivered a tens of pieces it is high-resolution on protein three-dimensional structure parse achievement, to life The reach of science generates significant impact, and Ice mapping is playing very important effect among these.
In order to reconstruct high-precision molecular structure, Ice mapping needs to shoot the high-definition picture of a large amount of two dimensions, by In Ice mapping is difficult to avoid such as owing coke in shooting process the problems such as, so as to cause to lose some image informations, in order to The loss of effective information is avoided, Ice mapping would generally shoot a large amount of high-resolution under different deficient burnt horizontal and different angles The two dimensional image of rate is synthesized, and to make up the information of single image loss, finally utilizes captured substantial amounts of high-resolution Two dimensional image, high-resolution molecular structure is reconstructed by relevant three-dimensionalreconstruction software such as Relion etc..
However, during three-dimensional molecular structure is reconstructed, in order to build accurate high-resolution three-dimensional molecular structure, Ice mapping needs to shoot substantial amounts of high-resolution two dimensional image from different angles, and subtle angle change is required to shoot Substantial amounts of two dimensional image in the case where Electronic Speculum is operated at full capacity, can generate the electron microscopic data of several tens TB daily, big with Tsing-Hua University Exemplified by learning Life Sciences Electronic Speculum platform Titan, the capture rate of every Titan 7GB/ minutes is that is, per minute to generate 7GB's or so Image data, such Electronic Speculum in one day with regard to can generate 7GB/ minutes it is * 60 minutes/hours * 24 small when=10.08TB number According to so as to cause every year the memory capacity for being up to 4PB will be consumed.
Big data is administered, and is a big problem of current generally existing.It divides and rule to data, i.e., it is other to carry out point door to data The personal management of class formula is the basic point of departure and principle of data management.For example, to cold data, non-emphasis data into line number It according to migration operation, is allowed to be deposited in low speed, low cost, mass-storage system, it is empty to exchange storage for using access time as cost Between and cost maximum return.In fact, this cost is completely can be received.
The label of data is the data that human experience judges, is the data after data.Tag control be realize data " point and Control it " a kind of important technology, be widely used in various big data systems.Generally speaking, " label " is the category of data Property label be human experience judge data, be the data after data.Tagging management is a very important trend.
But at present, the storage system of (freezing) electron microscopic data does not have label or only simple data label, still cannot Support big data analysis and the management of various dimensions.
The content of the invention
In view of this, the present invention provides a kind of electron microscopic data label and its generation method and generation system, can solve big Electron microscopic data label problem needed for the analysis and management of data system various dimensions.
