I want to use Neo4j to store a number of graphs I created in python. I was using Gephi for visualization, and I thought the export to Neo4j plugin would be a very simple way to get the data across. The problem is that the server is seemingly not recognizing the neostore...db files that Gephi generated.
I'm guessing I configured things incorrectly, but is there a way to fix that?
Alternatively, I'm also open to importing the files directly. I have two files: one with node titles and attributes and another with an edge list of title to title.
I'm guessing that I would need to convert the titles to ids, right? What would be the fastest way to do that?
Thank you in advance!
If you have the file as tab separated csv files, feel free to import them directly. There are some options, check out this page: http://www.neo4j.org/develop/import
Especially the CSV batch importer can help you: http://maxdemarzi.com/2012/02/28/batch-importer-part-1/
Or if it is just a little bit of data, use the spreadsheet approach: http://blog.neo4j.org/2013/03/importing-data-into-neo4j-spreadsheet.html
Please report back if you were successful.
I used Gephi to generate a neo4j store file directory in the past - it worked like a charm...
I assume you did delete the default graph.db directory and renamed your gephi-generated directory to graph.db? That worked for me...

I hope to get a solution here. I am completely new to R and really all i need it for is to extract data from power query and append it to an existing csv file. The only export approach that i have come across only works for exporting to the local c drive as per my example below. This approach however does not work for files in sharepoint with a URL. Can you please advise on a solution? Thanks
write.csv(dataset,"c:\\documents\\test.csv ,append=true")
I need your help over a problem I have. Actually, I have a page with a simple embed which displays a PDF file.
I got a request to add another PDF file to the same embed (or at least to do something which would look like it).
I searched some solutions and not finding a simple one, I'm thinking about using iTextSharp to merge both files (by getting their stream from their url), merging them into a new pdf file and display this resulting file into the embed.
But I'm just telling myself it's a bit too much for such a simple modification... And so I'm here asking you if someone would have a better idea ? From what I searched on stackoverflow and google it looks like I will have to take the merge solution but hey, we never know '^^
A simpler option would be to merge the two PDF files using either a free online tool or Adobe Combine Files option and then adding that newly combined PDF to your site. Unless I am missing something, there is no real reason or benefit to do this using code.
Basically i want it to import data from a SQL database and Display it as graphs. Having said that i also want it to be dynamic,responsive as in the users should have filtering options. Any leads would be definitely helpful.
Please note that i am just a beginner with drupal.
Yes, But I recommend you to work on your own framework. Or even you can use some data visualization framework
Maybe this one is useful for you if you want to do it on your own:

Why do you need Drupal for that?
I would make some PHP script which would read SQL and generate image out of that data, by using GD or ImageMagic lib. I guess you know that PHP can shoot out image file header and dynamically generate image, on fly. That PHP script could also read filter parameters to have influence on generated image.
I have a huge dataset value in JRDatasource object and am not able to export it to Excel as it will give me memory out of space error. So am planning to split the JRDatasource object and export the data part by part. Any idea or suggestion on how to implement this? Or any other way suggested also fine for me. Thanks in advance.
I dont know much about JRDataSource, but I'll offer another solution.
Take a look at Apache POI library which enables you to create excel files on-the-fly.
So you can read from the data source element by element and persist them on a excel file.
I found a link (http://wiki.alfresco.com/wiki/Content_Transformations) that says that i need to create a file named my-transformers-context.xml and put my configurations there to convert RTF to PDF...
There says that some configuration are already configured but this one (RTF to PDF) and some others (DOC to PDF) are not.
By the way i couldn't find how to create this xml with the right configuration to convert the RTF file into a PDF...
Someone already done something like this? or someone know a link that explain how to configure this xml file?
PROBLEM SOLVED!!!!
I don't know if there is a way to say that i've solved the problem... But here it goes the solution...
I saw what Gagravarr said and started looking for configuration of openoffice into alfresco...
There is a file named:
alfresco-global.properties
and there is two variables named:
ooo.exe
and
ooo.enabled
the first one must indicate the path to sopenoffice.exe
and the second one must be equal to true...
ooo.enabled = true
That solve a lot of problema to convert some kind of file to another... like RTF to PDF...
Out of the box, Alfresco should be able to transform a RTF file to a PDF using OpenOffice (direct or JodConverter, depending on if you're on Community or Enterprise)
Assuming you're on a new enough Alfresco, this webscript will tell you what transformations are available from and to RTF:
http://localhost:8080/alfresco/service/mimetypes?mimetype=application/rtf#application/rtf
If that doesn't show you RTF -> PDF, then you need to look at your open office configuration/setup
