This example shows in order a good simple SNP, a possible SNP that has been filtered out because its quality is below 10, a site at which two alternate alleles are called, with one of them (T) being ancestral (possibly a reference sequencing error), a site that is called monomorphic reference (i.e. There is an option whether to contain genotype information on samples for each position or not. It contains meta-information lines, a header line, and then data lines each containing information about a position in the genome. VCF is a text file format (most likely stored in a compressed manner). Please see VCF_4.0_sv for the conventions and extensions adopted by the 1000 Genomes Project for encoding structural variations in VCF 4.0 format. Details of the current version can be found with the HTS specifications. The VCF specification is now maintained by GA4GH.

It is therefore, recommended to use the vCard format over CSV when transferring contacts.Please note that this page describes version 4.0 of the VCF specification. Many programs and services such as iCloud, Gmail, Yahoo and Outlook (2007 or later versions) freely support the vCard format as a means of importing and exporting contacts. As a result, there is no data loss during the transfer of contacts via using the vCard format. vCard files are also widely supported by e-mail clients and services. vCard is superior to CSV in that it can store textual and numeric data, but also contact photos, and audio clips (i.e. VCard (also VCF) is a standardized method of storing and transferring contact data.

To find out more about how to do so, refer to the following tutorial: Transfer iPhone contacts to Hotmail vCard – the electronic business card standard You can use CopyTrans contacts to export iPhone contacts to Hotmail via a CSV file. (previously Hotmail) is one of these rare exceptions. It is rare nowadays for programs or services to only allow the transfer of contacts via CSV. Use CSV to transfer contacts in case there is no available alternative. In order to avoid text scrambling, you must ensure that both the program/service you use to export to CSV and the program/service you use to import or open the CSV file are designed to handle such non-standard scripts (check for utf8 and unicode).ĬopyTrans Contacts supports both special-characters and non-Latin scripts when exporting iOS contacts to CSV. Contact names containing non-Latin or special characters can get scrambled just as easily during the export stage as well as during the import stage. There are no set rules when it comes to defining how contact data is written to the CSV file by the originating program or service and how contact data is read by the destination program or service upon import.Īs CSV files can only store text and numeric data, non-textual and non-numeric content such as contact photos is lost during the transfer.įinally, there may be a number of problems occurring with non-Latin scripts (i.e.: Arab, Asian, Cyrillic, …) as well as with special characters (i.e.: é, ö, â). The biggest shortcoming of CSV is the lack of standardization. Nevertheless, CSV’s advantages end there. Many programs support a variation of CSV import and export. CSV can be particularly useful when transferring contacts between two or more contact programs or services which otherwise operate in mutually incompatible ways. CSV files – what’s hot and what’s notĬSV, also called comma- or character-separated values is a relatively simple format designed to store textual and numeric data (i.e.

When transferring contacts, it is important to understand in what ways these two common formats differ and when it is most appropriate to use one or the other. However, there are fundamental differences between CSV and vCard. Both CSV and vCard formats are used as a common way of transferring contacts between programs and services.
