geometry - R/ImageJ: Measuring shortest distance between points and curves -

i have experience r statistics platform, inexperienced in image based maths. have series of photographs (tiff format, px/µm known) holes , irregular curves. i'd measure shortest distance between hole , closest curve particular hole. i'd each hole in photograph. holes not regular either, maybe i'd need tell programme holes , curves (imagej has point , segmented line functions).

any ideas how this? bundle should utilize in r? recommend programme kind of task?

edit: doing possible using sclero package. bundle available on github , procedure described in detail in the tutorial. illustrate, utilize illustration tutorial:

library(devtools) install_github("mikkovihtakari/sclero", dependencies = true) library(sclero) path <- file.path(system.file("extdata", bundle = "sclero"), "shellspots.zip") dat <- read.ijdata(path, scale = 0.7812, unit = "um") shell <- convert.ijdata(dat) aligned <- spot.dist(shell) plot(aligned)

it possible add together sample spot sizes using functions provided sclero package. please see section 2.5 in tutorial.

How do I check if an insert was successful with MySQLdb in Python? -

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
