# Reading Data

This section demonstrates how the `isx` package can be used to read data from Inscopix files.
Refer to the [file types](../overview) table for reference on the Inscopix file types and read support.

:::{note}
The following sections assume the `isx` package has been imported, i.e., `import isx`
:::

## Microscope & Behavior Movies

`Microscope Movie` and `Behavior Movie` file types can be read using the `isx.Movie` class.

```python
# Open the movie for reading
movie = isx.Movie.read("movie.isxd")
```

Movie objects have timing and spacing properties which can be accessed:


```python
# Timing information can be accessed using:
movie.timing

# The number of frames can be accessed using:
movie.timing.num_samples

# The time period can be accessed using:
movie.timing.period.secs_float

# Spacing information can be accessed using:
movie.spacing

# The dimensions of the frame can be accessed using:
# which will return a 2-tuple containing the dimensions of the frame
# (num_rows, num_cols), or (height, width)
movie.spacing.num_pixels
```

Frames from movies can be read into memory:

```python
# The pixel data type can accessed using:
movie.data_type

# Read every frame of the movie, and process it
for i in range(movie.timing.num_samples):
# Dimensions of the frame are (num_rows, num_cols), or (height, width)
frame = movie.get_frame_data(i)

# Process frame
...
```

::: {warning}
It's recommended to read one frame into memory at a time to prevent out of memory errors.
:::

::: {note}
Python indexes by 0, so the first frame is at index 0, and the the second frame is at index 1, and so on.
:::

## Cell Sets

`Cell Set` file types can be read using the `isx.CellSet` class.

```python
# Open the cell set for reading
cell_set = isx.CellSet.read("cell_set.isxd")
```

Similar to movies, cell sets have timing and spacing properties which can be accessed.
These properties are derived from the parent movie which generated the cell set.

```python
# Timing information can be accessed using:
cell_set.timing

# The number of frames can be accessed using:
cell_set.timing.num_samples

# The time period can be accessed using:
cell_set.timing.period.secs_float

# Spacing information can be accessed using:
cell_set.spacing

# The dimensions of the frame can be accessed using:
# which will return a 2-tuple containing the dimensions of the frame
# (num_rows, num_cols), or (height, width)
cell_set.spacing.num_pixels
```

Cell data from cell sets can be read into memory:

```python
# The number of cells in the cell set can accessed using:
cell_set.num_cells

# Read data of every cell in the cell set, and process it
for i in range(cell_set.num_cells):
# Get the cell name
name = cell_set.get_cell_name(i)

# Get the temporal activity trace of a cell
trace = cell_set.get_cell_trace(i)

# Get the spatial footprint of a cell
footprint = cell_set.get_cell_image_data(i)

# Process cell data
...
```

## Event Sets

`Event Set` file types can be read using the `isx.EventSet` class.

```python
# open the event set for reading
event_set = isx.EventSet.read("event_set.isxd")
```

Similar to cell sets, event sets have timing properties which can be accessed.
These properties are derived from the parent cell set which generated the event set.

```python
# Timing information can be accessed using:
event_set.timing

# The number of frames can be accessed using:
event_set.timing.num_samples

# The time period can be accessed using:
event_set.timing.period.secs_float
```

Cell data from event sets can be read into memory:

```python
# Read data of every cell in the event set, and process it
for i in range(event_set.timing.num_samples):
# Get the cell name
name = event_set.get_cell_name(i)

# Get the event timestamps and amplitudes of a cell
offsets, amplitudes = event_set.get_cell_data(i)

# Process cell data
...
```

## Vessel Sets

`Vessel Set` file types can be read using the `isx.VesselSet` class.

```python
# Open the vessel set for reading
vessel_set = isx.VesselSet.read("vessel_set.isxd")
```

Similar to movies, vessel sets have timing and spacing properties which can be accessed.
These properties are derived from the parent movie which generated the vessel set.

```python
# Timing information can be accessed using:
vessel_set.timing

# The number of frames can be accessed using:
vessel_set.timing.num_samples

# The time period can be accessed using:
vessel_set.timing.period.secs_float

# Spacing information can be accessed using:
vessel_set.spacing

# The dimensions of the frame can be accessed using:
# which will return a 2-tuple containing the dimensions of the frame
# (num_rows, num_cols), or (height, width)
vessel_set.spacing.num_pixels
```

Vessel data from vessel sets can be read into memory:

```python
# The number of vessels in the vessel set can be accessed using:
vessel_set.num_vessels

# The standard deviation projection image of the parent movie
# This is the same for every vessel
image = vessel_set.get_vessel_image_data(0)

# Read data of every vessel in the vessel set, and process it
for i in range(vessel_set.num_vessels):
# Get the vessel name
name = vessel_set.get_vessel_name(i)

# Get the vessel status
status = vessel_set.get_vessel_status(i)

# For vessel diameter vessel sets, get the following data:
# The vessel diameter trace
trace = vessel_set.get_vessel_trace_data(i)
# The direction of rbc velocity trace
center_trace = vessel_set.get_vessel_center_trace_data(i)
# The vessel line points
line = vessel_set.get_vessel_line_data(i)

# For rbc velocity vessel sets, get the following data:
# The rbc velocity trace
trace = vessel_set.get_vessel_trace_data(i)
# The direction of rbc velocity trace
direction_trace = vessel_set.get_vessel_direction_trace_data(i)
# The first correlation heatmap of the vessel
corr = vessel_set.get_vessel_correlations_data(i, 0)
# The vessel box points
box = vessel_set.get_vessel_line_data(i)

# Process vessel data
...
```

## GPIO & IMU

`GPIO` and `IMU` file types can be read using the `isx.GpioSet` class.

```python
# open the gpio set for reading
gpio_set = isx.GpioSet.read("signals.gpio")
```

Gpio sets have timing properties which can be accessed.

```python
# Timing information can be accessed using:
gpio_set.timing

# The number of frames can be accessed using:
gpio_set.timing.num_samples

# The time period can be accessed using:
gpio_set.timing.period.secs_float
```

Signal data from gpio sets can be read into memory:

```python
# Number of channels (i.e., signals) can be accessed using:
gpio_set.num_channels

# Read data of every cell in the cell set, and process it
for i in range(gpio_set.num_channels):
# Get the channel name
name = gpio_set.get_channel_name(i)

# Get the signal timestamps and amplitudes of a channel
offsets, amplitudes = gpio_set.get_channel_data(i)

# Process signal data
...
```
