extract

I have multiple zip files with names such as 001.zip, 002.zip, 003.zip and have the potential to go up to 999.zip. Each zip file has exactly one text file. I would like to extract each zip file using Batch, and then rename the text file it extracted to the file name of the zip. For example, if I extract 001.zip, I want the text file that gets extracted (all the text files that get extracted have different names) to be name 001.txt. I at least am extracting all the files right now, but I am too unfamiliar with Batch, and am not sure if there is a simple way to do this? cd test echo

I am relatively new on R. I am trying to get time series of different points ( lat, lon) of temperature data from a netCDF file. My sample data file is here and here is the small file . I have tried netCDF package and the code i have used so far library(ncdf) obsdata = open.ncdf("obs.nc") print.ncdf(obsdata) obsdatadates = obsdata$dim$time$vals obsdatadates = as.Date(obsdatadates,origin = '1950-01-01') obsdatadates obsoutput = get.var.ncdf(obsdata, varid = 'tasmin', start = c(1,1,1), count = c(1,1,22280)) dim(obsoutput) datafinal=merge(obsdatadates,obsoutput) Can anyone help me to get a

I have a string "Name(something)" and I am trying to extract the portion of the string within the parentheses! Iv'e tried the following solutions but don't seem to be getting the results I'm looking for. n.split('()') name, something = n.split('()') Maroun You can use a simple regex to catch everything between the parenthesis: >>> import re >>> s = 'Name(something)' >>> re.search('\(([^)]+)', s).group(1) 'something' The regex matches the first "(", then it matches everything that's not a ")": \( matches the character "(" literally the capturing group ([^)]+) greedily matches anything that's

I want to write a python program that could extract audio from a video file (e.g. video.avi ). Is there any good library for it? And where should I start from? I tried to use PyMedia, but I couldn't install it on my MacOSX(Mountain Lion). EDIT: The problem is video.avi is not completely available. Someone is writing on it and adding some frames to it every second. So I wanted to write a code in python to get the video as it comes and extract the audio from it and write it to a file (e.g. audio.mp3 , audio.wav ). I don't know if ffmpeg can wait for the video to be copied to video.avi . And I

xml looks like so: <statements> <statement account="123"> ...stuff... </statement> <statement account="456"> ...stuff... </statement> </statements> I'm using stax to process one " <statement> " at a time and I got that working. I need to get that entire statement node as a string so I can create "123.xml" and "456.xml" or maybe even load it into a database table indexed by account. using this approach: http://www.devx.com/Java/Article/30298/1954 I'm looking to do something like this: String statementXml = staxXmlReader.getNodeByName("statement"); //load statementXml into database Why not just

i guess this is a common problem, and i found quite a lot of webpages, including some from SO, but i failed to understand how to implement it. I am new to REGEX, and I'd like to use it in R to extract the first few words from a sentence. for example, if my sentence is z = "I love stack overflow it is such a cool site" id like to have my output as being (if i need the first four words) [1] "I love stack overflow" or (if i need the last four words) [1] "such a cool site" of course, the following works paste(strsplit(z," ")[[1]][1:4],collapse=" ") paste(strsplit(z," ")[[1]][7:10],collapse=" ")

I want to create a network based on the weight of keywords from text. Then I got an error when running the codes related to tm_map: library (tm) library(NLP) lirary (openNLP) text = c('.......') corp <- Corpus(VectorSource(text)) corp <- tm_map(corp, stripWhitespace) Warning message: In tm_map.SimpleCorpus(corp, stripWhitespace) : transformation drops documents corp <- tm_map(corp, tolower) Warning message: In tm_map.SimpleCorpus(corp, tolower) : transformation drops documents The codes were working 2 months ago, now I'm trying for a new data and it is not working anymore. Anyone please shows
